What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism .

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

How to write a literature review for a dissertation, published by steve tippins on july 5, 2019 july 5, 2019.

Last Updated on: 22nd May 2024, 04:06 am

Chapter 2 of your dissertation, your literature review, may be the longest chapter. It is not uncommon to see lit reviews in the 40- to 60-page range. That may seem daunting, but I contend that the literature review could be the easiest part of your dissertation.

It is also foundational. To be able to select an appropriate research topic and craft expert research questions, you’ll need to know what has already been discovered and what mysteries remain. 

Remember, your degree is meant to indicate your achieving the highest level of expertise in your area of study. The lit review for your dissertation could very well form the foundation for your entire career.

In this article, I’ll give you detailed instructions for how to write the literature review of your dissertation without stress. I’ll also provide a sample outline.

When to Write the Literature Review for your Dissertation

Though technically Chapter 2 of your dissertation, many students write their literature review first. Why? Because having a solid foundation in the research informs the way you write Chapter 1.

Also, when writing Chapter 1, you’ll need to become familiar with the literature anyway. It only makes sense to write down what you learn to form the start of your lit review.

Some institutions even encourage students to write Chapter 2 first. But it’s important to talk with your Chair to see what he or she recommends.

How Long Should a Literature Review Be?

There is no set length for a literature review. The length largely depends on your area of study. However, I have found that most literature reviews are between 40-60 pages.

If your literature review is significantly shorter than that, ask yourself (a) if there is other relevant research that you have not explored, or (b) if you have provided enough of a discussion about the information you did explore.

Preparing to Write the Literature Review for your Dissertation

Step 1. Search Using Key Terms

Most people start their lit review searching appropriate databases using key terms. For example, if you’re researching the impact of social media on adult learning, some key terms you would use at the start of your search would be adult learning, androgogy, social media, and “learning and social media” together. 

If your topic was the impact of natural disasters on stock prices, then you would need to explore all types of natural disasters, other market factors that impact stock prices, and the methodologies used. 

You can save time by skimming the abstracts first; if the article is not what you thought it might be you can move on quickly.

Once you start finding articles using key terms, two different things will usually happen: you will find new key terms to search, and the articles will lead you directly to other articles related to what you are studying. It becomes like a snowball rolling downhill. 

Note that the vast majority of your sources should be articles from peer-reviewed journals. 

Step 2. Immerse Yourself in the Literature

When people ask what they should do first for their dissertation the most common answer is “immerse yourself in the literature.” What exactly does this mean?

Think of this stage as a trip into the quiet heart of the forest. Your questions are at the center of this journey, and you’ll need to help your reader understand which trees — which particular theories, studies, and lines of reasoning — got you there. 

There are lots of trees in this particular forest, but there are particular trees that mark your path.  What makes them unique? What about J’s methodology made you choose that study over Y’s? How did B’s argument triumph over A’s, thus leading you to C’s theory? 

You are showing your reader that you’ve fully explored the forest of your topic and chosen this particular path, leading to these particular questions (your research questions), for these particular reasons.

Step 3. Consider Gaps in the Research

The gaps in the research are where current knowledge ends and your study begins. In order to build a case for doing your study, you must demonstrate that it:

• Is worthy of doctoral-level research, and
• Has not already been studied

Defining the gaps in the literature should help accomplish both aims. Identifying studies on related topics helps make the case that your study is relevant, since other researchers have conducted related studies.

And showing where they fall short will help make the case that your study is the appropriate next step. Pay special attention to the recommendations for further research that the authors of studies make.

Step 4. Organize What You Find

As you find articles, you will have to come up with methods to organize what you find. 

Whether you find a computer-based system (three popular systems are Zotero, endNote, and Mendeley) or some sort of manual system such as index cards, you need to devise a method where you can easily group your references by subject and methodology and find what you are looking for when you need it. It is very frustrating to know you have found an article that supports a point that you are trying to make, but you can’t find the article!

One way to save time and keep things organized is to cut and paste relevant quotations (and their references) under topic headings. You’ll be able to rearrange and do some paraphrasing later, but if you’ve got the quotations and the citations that are important to you already embedded in your text, you’ll have an easier time of it.  

If you choose this method, be sure to list the whole reference on the reference/bibliography page so you don’t have to do this page separately later. Some students use Scrivener for this purpose, as it offers a clear way to view and easily navigate to all sections of a written document.

How to Write the Literature Review for your Dissertation

Once you have gathered a sufficient number of pertinent references, you’ll need to string them together in a way that tells your story. Explain what previous researchers have done by telling the story of how knowledge on this topic has evolved. Here, you are laying the support for your topic and showing that your research questions need to be answered. Let’s dive into how to actually write your dissertation’s literature review.

Step 1. Create an Outline

If you’ve created a system for keeping track of the sources you’ve found, you likely already have the bones of an outline. Even if not, it may be relatively easy to see how to organize it all. The main thing to remember is, keep it simple and don’t overthink it. There are several ways to organize your dissertation’s literature review, and I’ll discuss some of the most common below:

• By topic. This is by far the most common approach, and it’s the one I recommend unless there’s a clear reason to do otherwise. Topics are things like servant leadership, transformational leadership, employee retention, organizational knowledge, etc. Organizing by topic is fairly simple and it makes sense to the reader.
• Chronologically. In some cases, it makes sense to tell the story of how knowledge and thought on a given subject have evolved. In this case, sub-sections may indicate important advances or contributions. 
• By methodology. Some students organize their literature review by the methodology of the studies. This makes sense when conducting a mixed-methods study, and in cases where methodology is at the forefront.

Step 2. Write the Paragraphs 

I said earlier that I thought the lit review was the easiest part to write, and here is why. When you write about the findings of others, you can do it in small, discrete time periods. You go down the path awhile, then you rest. 

Once you have many small pieces written, you can then piece them together. You can write each piece without worrying about the flow of the chapter; that can all be done at the end when you put the jigsaw puzzle of references together.

Step 3. Analyze

The literature review is a demonstration of your ability to think critically about existing research and build meaningfully on it in your study. Avoid simply stating what other researchers said. Find the relationships between studies, note where researchers agree and disagree, and– especiallyy–relate it to your own study. 

Pay special attention to controversial issues, and don’t be afraid to give space to researchers who you disagree with. Including differing opinions will only strengthen the credibility of your study, as it demonstrates that you’re willing to consider all sides.

Step 4. Justify the Methodology

In addition to discussing studies related to your topic, include some background on the methodology you will be using. This is especially important if you are using a new or little-used methodology, as it may help get committee members onboard. 

I have seen several students get slowed down in the process trying to get committees to buy into the planned methodology. Providing references and samples of where the planned methodology has been used makes the job of the committee easier, and it will also help your reader trust the outcomes.

Advice for Writing Your Dissertation’s Literature Review

• Remember to relate each section back to your study (your Problem and Purpose statements).
• Discuss conflicting findings or theoretical positions. Avoid the temptation to only include research that you agree with.
• Sections should flow together, the way sections of a chapter in a nonfiction book do. They should relate to each other and relate back to the purpose of your study. Avoid making each section an island.
• Discuss how each study or theory relates to the others in that section.
• Avoid relying on direct quotes–you should demonstrate that you understand the study and can describe it accurately.

Sample Outline of a Literature Review (Dissertation Chapter 2)

Here is a sample outline, with some brief instructions. Note that your institution probably has specific requirements for the structure of your dissertation’s literature review. But to give you a general idea, I’ve provided a sample outline of a dissertation ’s literature review here.

• Introduction
• State the problem and the purpose of the study
• Give a brief synopsis of literature that establishes the relevance of the problem
• Very briefly summarize the major sections of your chapter

Documentation of Literature Search Strategy

• Include the library databases and search engines you used
• List the key terms you used
• Describe the scope (qualitative) or iterative process (quantitative). Explain why and based on what criteria you selected the articles you did.

Literature Review (this is the meat of the chapter)

• Sub-topic a
• Sub-topic b
• Sub-topic c

See below for an example of what this outline might look like.

How to Write a Literature Review for a Dissertation: An Example 

Let’s take an example that will make the organization, and the outline, a little bit more clear. Below, I’ll fill out the example outline based on the topics discussed.

If your questions have to do with the impact of the servant leadership style of management on employee retention, you may want to saunter down the path of servant leadership first, learning of its origins , its principles , its values , and its methods . 

You’ll note the different ways the style is employed based on different practitioners’ perspectives or circumstances and how studies have evaluated these differences. Researchers will draw conclusions that you’ll want to note, and these conclusions will lead you to your next questions. 

Next, you’ll want to wander into the territory of management styles to discover their impact on employee retention in general. Does management style really make a difference in employee retention, and if so, what factors, exactly, make this impact?

Employee retention is its own path, and you’ll discover factors, internal and external, that encourage people to stick with their jobs.

You’ll likely find paradoxes and contradictions in here that just bring up more questions. How do internal and external factors mix and match? How can employers influence both psychology and context ? Is it of benefit to try and do so?

At first, these three paths seem somewhat remote from one another, but your interest is where the three converge. Taking the lit review section by section like this before tying it all together will not only make it more manageable to write but will help you lead your reader down the same path you traveled, thereby increasing clarity. 

Example Outline

So the main sections of your literature review might look something like this:

• Literature Search Strategy
• Conceptual Framework or Theoretical Foundation
• Literature that supports your methodology
• Origins, principles, values
• Seminal research
• Current research
• Management Styles’ Impact on employee retention
• Internal Factors
• External Factors
• Influencing psychology and context
• Summary and Conclusion

Final Thoughts on Writing Your Dissertation’s Chapter 2

The lit review provides the foundation for your study and perhaps for your career. Spend time reading and getting lost in the literature. The “aha” moments will come where you see how everything fits together. 

At that point, it will just be a matter of clearly recording and tracing your path, keeping your references organized, and conveying clearly how your research questions are a natural evolution of previous work that has been done.

Overview of writing the literature review

Conducting a literature review enables you to demonstrate your understanding and knowledge of the existing work within your field of research. Doing so allows you to identify any underdeveloped areas or unexplored issues within a specific debate, dialogue or field of study. This, in turn, helps you to clearly and persuasively demonstrate how your own research will address one or more of these gaps.

Disciplinary differences

Please note: this guide is not specific to any one discipline. The literature review can vary depending on the nature of the research and the expectations of the school or department. Please adapt the following advice to meet the demands of your dissertation and the expectations of your school or department. Consult your supervisor for further guidance; you can also check out  Writing Across Subjects guide .

Guide contents

As part of the Writing the Dissertation series, this guide covers the most common expectations for the literature review chapter, giving you the necessary knowledge, tips and guidance needed to impress your markers!  The sections are organised as follows:

• Getting Started  - Defines the literature review and presents a table to help you plan.
• Process -  Explores choosing a topic, searching for sources and evaluating what you find.

What is the literature review?

The literature review of a dissertation gives a clear, critical overview of a specific area of research. Our main Writing the Dissertation - Overview and Planning guide explains how you can refine your dissertation topic  and begin your initial research; the next tab of this guide, 'Process', expands on those ideas. In summary, the process of conducting a literature review usually involves the following:

• Conducting a series of strategic searches to identify the key texts within that topic.
• Identifying the main argument in each source, the relevant themes and issues presented and how they relate to each other.
• Critically evaluating your chosen sources and determining their strengths, weaknesses, relevance and value to your research along with their overall contribution to the broader research field.
• Identifying any gaps or flaws in the literature which your research can address.

Literature review as both process and product

Writers should keep in mind that the phrase 'literature review' refers to two related, but distinct, things:

• 'Literature review' refers, first, to the  active process  of discovering and assessing relevant literature.
• 'Literature review' refers, second, to the  written product  that emerges from the above process.

This distinction is vital to note because  every  dissertation requires the writer to engage with and consider existing literature (i.e., to undertake the active  process ). Research doesn't exist in a void, and it's crucial to consider how our work builds from or develops existing foundations of thought or discovery. Thus, even if your discipline doesn't require you to include a chapter titled 'Literature Review' in your submitted dissertation, you should expect to engage with the process of reviewing literature.

Why is it important to be aware of existing literature?

• You are expected to explain how your research fits in with other research in your field and, perhaps, within the wider academic community.
• You will be expected to contribute something new, or slightly different, so you need to know what has already been done.
• Assessing the existing literature on your topic helps you to identify any gaps or flaws within the research field. This, in turn, helps to stimulate new ideas, such as addressing any gaps in knowledge, or reinforcing an existing theory or argument through new and focused research.

Not all literature reviews are the same. For example, in many subject areas, you are expected to include the literature review as its own chapter in your dissertation. However, in other subjects, the dissertation structure doesn't include a dedicated literature review chapter; any literature the writer has reviewed is instead incorporated in other relevant sections such as the introduction, methodology or discussion.

For this reason, there are a number of questions you should discuss with your supervisor before starting your literature review. These questions are also great to discuss with peers in your degree programme. These are outlined in the table below (see the Word document for a copy you can save and edit):

• Dissertation literature review planning table

Literature review: the process

Conducting a literature review requires you to stay organised and bring a systematic approach to your thinking and reading. Scroll to continue reading, or click a link below to jump immediately to that section:

Choosing a topic

The first step of any research project is to select an interesting topic. From here, the research phase for your literature review helps to narrow down your focus to a particular strand of research and to a specific research question. This process of narrowing and refining your research topic is particularly important because it helps you to maintain your focus and manage your material without becoming overwhelmed by sources and ideas.

Try to choose something that hasn’t been researched to death. This way, you stand a better chance of making a novel contribution to the research field.

Conversely, you should avoid undertaking an area of research where little to no work has been done. There are two reasons for this:

• Firstly, there may be a good reason for the lack of research on a topic (e.g. is the research useful or worthwhile pursuing?).
• Secondly, some research projects, particularly practice-based ones involving primary research, can be too ambitious in terms of their scope and the availability of resources. Aim to contribute to a topic, not invent one!

Searching for sources

Researching and writing a literature review is partly about demonstrating your independent research skills. Your supervisor may have some tips relating to your discipline and research topic, but you should be proactive in finding a range of relevant sources. There are various ways of tracking down the literature relevant to your project, as outlined below.

Make use of Library Search

One thing you don’t want to do is simply type your topic into Google and see what comes up. Instead, use Library Search to search the Library’s catalogue of books, media and articles.

Online training for 'Using databases' and 'Finding information' can be found here . You can also use the Library's subject pages to discover databases and resources specific to your academic discipline.

Engage with others working in your area

As well as making use of library resources, it can be helpful to discuss your work with students or academics working in similar areas. Think about attending relevant conferences and/or workshops which can help to stimulate ideas and allows you to keep track of the most current trends in your research field.

Look at the literature your sources reference

Finding relevant literature can, at times, be a long and slightly frustrating experience. However, one good source can often make all the difference. When you find a good source that is both relevant and valuable to your research, look at the material it cites throughout and follow up any sources that are useful. Also check if your source has been cited in any more recent publications.

Think of the bibliography/references page of a good source as a series of breadcrumbs that you can follow to find even more great material.

Evaluating sources

It is very important to be selective when choosing the final sources to include in your literature review. Below are some of the key questions to ask yourself:

• If a source is tangentially interesting but hasn’t made any particular contribution to your topic, it probably shouldn’t be included in your literature review. You need to be able to demonstrate how it fits in with the other sources under consideration, and how it has helped shape the current state of the literature.
• There might be a wealth of material available on your chosen subject, but you need to make sure that the sources you use are appropriate for your assignment. The safest approach to take is to use only academic work from respected publishers. However, on occasions, you might need to deviate from traditional academic literature in order to find the information you need. In many cases, the problem is not so much the sources you use, but how you use them. Where relevant, information from newspapers, websites and even blogs are often acceptable, but you should be careful how you use that information. Do not necessarily take any information as factual. Instead be critical and interpret the material in the context of your research. Consider who the writer is and how this might influence the authority and reliability of the information presented. Consult your supervisor for more specific guidance relating to your research.
• The mere fact that something has been published does not automatically guarantee its quality, even if it comes from a reputable publisher. You will need to critique the content of the source. Has the author been thorough and consistent in their methodology? Do they present their thesis coherently? Most importantly, have they made a genuine contribution to the topic?

Keeping track of your sources

Once you have selected a source to use in your literature review, it is useful to make notes on all of its key features, including where it comes from, what it says, and what its main strengths and weaknesses are. This way you can easily re-familiarise yourself with a source without having to re-read it. Keeping an annotated bibliography or completing source evaluation tables are a couple ways to do this.

Digital notebooks such as OneNote are another great option. You can keep all your notes and evaluation in one place, organising according to either subtopics/themes or sources. Customise the sections and pages of your notebook so it is easy to navigate and feels intuitive to how you think and process information. The video below will help you get started.

Writing your literature review

As we explored in the 'Getting Started' tab, the literature review is both a process you follow and (in most cases) a written chapter you produce. Thus, having engaged the review process, you now need to do the writing itself. Please continue reading, or click a heading below to jump immediately to that section.

Guiding principles

The structure of the final piece will depend on the discipline within which you are working as well as the nature of your particular research project. However, here are a few general pieces of advice for writing a successful literature review:

• Show the connections between your sources. Remember that your review should be more than merely a list of sources with brief descriptions under each one. You are constructing a narrative. Show clearly how each text has contributed to the current state of the literature, drawing connections between them.
• Engage critically with your sources. This means not simply describing what they say. You should be evaluating their content: do they make sound arguments? Are there any flaws in the methodology? Are there any relevant themes or issues they have failed to address? You can also compare their relative strengths and weaknesses.
• Signpost throughout to ensure your reader can follow your narrative.  Keep relating the discussion back to your specific research topic.
• Make a clear argument. Keep in mind that this is a chance to present your take on a topic. Your literature review showcases your own informed interpretation of a specific area of research. If you have followed the advice given in this guide you will have been careful and selective in choosing your sources. You are in control of how you present them to your reader.

There are several different ways to structure the literature review chapter of your dissertation. Two of the most common strategies are thematic structure and chronological structure (the two of which can also be combined ). However you structure the literature review, this section of the dissertation normally culminates in identifying the research gap.

Thematic structure

Variations of this structure are followed in most literature reviews. In a thematic structure , you organise the literature into groupings by theme (i.e., subtopic or focus). You then arrange the groupings in the most logical order, starting with the broadest (or most general) and moving to the narrowest (or most specific).

The funnel or inverted pyramid

To plan a thematic structure structure, it helps to imagine your themes moving down a funnel or inverted pyramid  from broad to narrow. Consider the example depicted below, which responds to this research question:

What role did the iron rivets play in the sinking of the Titanic?

The topic of maritime disasters is the broadest theme, so it sits at the broad top of the funnel. The writer can establish some context about maritime disasters, generally, before narrowing to the Titanic, specifically. Next, the writer can narrow the discussion of the Titanic to the ship's structural integrity, specifically. Finally, the writer can narrow the discussion of structural integrity to the iron rivets, specifically. And voila: there's the research gap!

The broad-to-narrow structure is intuitive for readers. Thus, it is crucial to consider how your themes 'nest inside' one another, from the broad to the narrow. Picturing your themes as nesting dolls is another way to envision this literature review structure, as you can see in the image below.

As with the funnel, remember that the first layer (or in this case, doll) is largest because it represents the broadest theme. In terms of word count and depth, the tinier dolls will warrant more attention because they are most closely related to the research gap or question(s).

The multi-funnel variation

The example above demonstrates a research project for which one major heading might suffice, in terms of outlining the literature review. However, the themes you identify for your dissertation might not relate to one another in such a linear fashion. If this is the case, you can adapt the funnel approach to match the number of major subheadings you will need.

In the three slides below, for example, a structure is depicted for a project that investigates this (fictional) dissertation research question: does gender influence the efficacy of teacher-led vs. family-led learning interventions for children with ADHD? Rather than nesting all the subtopics or themes in a direct line, the themes fall into three major headings.

The first major heading explores ADHD from clinical and diagnostic perspectives, narrowing ultimately to gender:

• 1.1 ADHD intro
• 1.2 ADHD definitions
• 1.3 ADHD diagnostic criteria
• 1.4 ADHD gender differences

The second major heading explores ADHD within the classroom environment, narrowing to intervention types:

• 2.1 ADHD in educational contexts
• 2.2 Learning interventions for ADHD
• 2.2.1 Teacher-led interventions
• 2.2.2 Family-led interventions

The final major heading articulates the research gap (gender differences in efficacy of teacher-led vs. family-led interventions for ADHD) by connecting the narrowest themes of the prior two sections.

Multi-funnel literature review structure by Academic Skills Service

To create a solid thematic structure in a literature review, the key is thinking carefully and critically about your groupings of literature and how they relate to one another. In some cases, your themes will fit in a single funnel. In other cases, it will make sense to group your broad-to-narrow themes under several major headings, and then arrange those major headings in the most logical order.

Chronological structure

Some literature reviews will follow a  chronological structure . As the name suggests, a review structured chronologically will arrange sources according to their publication dates, from earliest to most recent.

This approach can work well when your priority is to demonstrate how the research field has evolved over time. For example, a chronological arrangement of articles about artificial intelligence (AI) would allow the writer to highlight how breakthroughs in AI have built upon one another in sequential order.

A chronological structure can also suit literature reviews that need to capture how perceptions or understandings have developed across a period of time (including to the present day). For example, if your dissertation involves the public perception of marijuana in the UK, it  could  make sense to arrange that discussion chronologically to demonstrate key turning points and changes of majority thought.

The chronological structure can work well in some situations, such as those described above. That being said, a purely chronological structure should be considered with caution.  Organising sources according to date alone runs the risk of creating a fragmented reading experience. It can be more difficult in a chronological structure to properly synthesize the literature. For these reasons, the chronological approach is often blended into a thematic structure, as you will read more about, below.

Combined structures

The structures of literature reviews can vary drastically, and for any given dissertation there will be many valid ways to arrange the literature.

For example, many literature reviews will  combine  the thematic and chronological approaches in different ways. A writer might match their major headings to themes or subtopics, but then arrange literature chronologically within the major themes identified. Another writer might base their major headings on chronology, but then assign thematic subheadings to each of those major headings.

When considering your options, try to imagine your reader or audience. What 'flow' will allow them to best follow the discussion you are crafting? When you are reading articles, what structural approaches do you appreciate in terms of ease and clarity?

Identifying the gap

The bulk of your literature review will explore relevant points of development and scholarly thought in your research field: in other words, 'Here is what has been done so far, thus here is where the conversation now stands'. In that way, you position your project within a wider academic discussion.

Having established that context, the literature review generally culminates in an articulation of what remains to be done: the  research gap  your project addresses. See the next tab for further explanation and examples.

Demystifying the research gap

The term research gap   is intimidating for many students, who might mistakenly believe that every single element of their research needs to be brand new and fully innovative. This isn't the case!

The gap in many projects will be rather niche or specific. You might be helping to update or re-test knowledge rather than starting from scratch. Perhaps you have repeated a study but changed one variable. Maybe you are considering a much discussed research question, but with a lesser used methodological approach.

To demonstrate the wide variety of gaps a project could address, consider the examples below. The categories used and examples included are by no means comprehensive, but they should be helpful if you are struggling to articulate the gap your literature review has identified.

***P lease note that the content of the example statements has been invented for the sake of demonstration. The example statements should not be taken as expressions of factual information.

Gaps related to population or geography

Many dissertation research questions involve the study of a specific population. Those populations can be defined by nationality, ethnicity, gender, sexuality, socioeconomic class, political beliefs, religion, health status, or other factors. Other research questions target a specific geography (e.g. a country, territory, city, or similar). Perhaps your broader research question has been pursued by many prior scholars, but few (or no) scholars have studied the question in relation to your focal population or locale: if so, that's a gap.

• Example 1:  As established above, the correlations between [ socioeconomic status ] and sustainable fashion purchases have been widely researched. However, few studies have investigated the potential relationship between [ sexual identity ] and attitudes toward sustainable fashion. Therefore...
• Example 2:  Whilst the existing literature has established a clear link between [ political beliefs ] and perceptions of socialized healthcare, the influence of [ religious belief ] is less understood, particularly in regards to [ Religion ABC ].
• Example 3:  Available evidence confirms that the widespread adoption of Technology XYZ in [ North America ] has improved manufacturing efficiency and reduced costs in the automotive sector. Using predictive AI models, the present research seeks to explore whether deployment of Technology XYZ could benefit the automotive sector of [ Europe ] in similar ways.

Gaps related to theoretical framework

The original contribution might involve examining something through a new lens.  Theoretical framework  refers, most simply, to the theory or theories a writer will use to make sense of and shape (i.e., frame ) their discussion. Perhaps your topic has been analysed in great detail through certain theoretical lenses, but you intend to frame your analysis using a theory that fewer scholars have applied to the topic: if so, that's a gap.

• Example 1:  Existing discussions of the ongoing revolution in Country XYZ frame the unrest in terms of [ theory A ] and [ theory B ]. The present research will instead analyse the situation using [ theory C ], allowing greater insight into...
• Example 2:  In the first section of this literature review, I examined the [ postmodern ], [ Marxist ], and [ pragmatist ] analyses that dominate academic discussion of The World According to Garp.  By revisiting this modern classic through the lens of [ queer theory ], I intend to...

Gaps related to methodological approach

The research gap might be defined by differences of methodology (see our Writing the Methodology guide for more). Perhaps your dissertation poses a central question that other scholars have researched, but they have applied different methods to find the answer(s): if so, that's a gap.

• Example 1:  Previous studies have relied largely upon the [ qualitative analysis of interview transcripts ] to measure the marketing efficacy of body-positive advertising campaigns. It is problematic that little quantitative data underpins present findings in this area. Therefore, I will address this research gap by [ using algorithm XYZ to quantify and analyse social-media interactions ] to determine whether...
• Example 2: Via [ quantitative and mixed-methods studies ], previous literature has explored how demographic differences influence the probability of a successful match on Dating App XYZ. By instead [ conducting a content analysis of pre-match text interactions ] on Dating App XYZ, I will...

Scarcity as a gap

Absolutes such as never  and always  rarely apply in academia, but here is an exception: in academia, a single study or analysis is  never  enough. Thus, the gap you address needn't be a literal void in the discussion. The gap could instead have to do with  replicability  or  depth/scope.  In these cases, you are adding value and contributing to the academic process by testing emerging knowledge or expanding underdeveloped discussions.

• Example:  Initial research points to the efficacy of Learning Strategy ABC in helping children with dyslexia build their reading confidence. However, as detailed earlier in this review, only four published studies have tested the intervention, and two of those studies were conducted in a laboratory. To expand our growing understanding of how Learning Strategy ABC functions in classroom environments, I will...

Elapsed time as a gap

Academia values up-to-date knowledge and findings, so another valid type of gap relates to elapsed time. Many factors that can influence or shape research findings are ever evolving: technology, popular culture, and political climates, to name just a few. Due to such changes, it's important for scholars in most fields to continually update findings. Perhaps your dissertation adds value by contributing to this process.

For example, imagine if a scholar today were to rely on a handbook of marketing principles published in 1998. As good as that research might have been in 1998, technology (namely, the internet) has advanced drastically since then. The handbook's discussion of online marketing strategies will be laughably outdated when compared to more recent literature.

• Example:  A wide array of literature has explored the ways in which perceptions of gender influence professional recruitment practices in the UK. The bulk of said literature, however, was published prior to the #MeToo movement and resultant shifts in discourse around gender, power imbalances and professional advancement. Therefore...

What to avoid

This portion of the guide will cover some common missteps you should try to avoid in writing your literature review. Scroll to continue reading, or click a heading below to jump immediately to that section.

Writing up before you have read up

Trying to write your literature review before you have conducted adequate research is a recipe for panic and frustration. The literature review, more than any other chapter in your dissertation, depends upon your critical understanding of a range of relevant literature. If you have only dipped your toe into the pool of literature (rather than diving in!), you will naturally struggle to develop this section of the writing. Focus on developing your relevant bases of knowledge before you commit too much time to drafting.

Believing you need to read everything

As established above, a literature review does require a significant amount of reading. However, you aren't expected to review  everything ever written  about your topic. Instead, aim to develop a more strategic approach to your research. A strategic approach to research looks different from one project to the next, but here are some questions to help you prioritise:

• If your field values up-to-date research and discoveries, carefully consider the 'how' and 'what' before investing time reading older sources: how will the source function in your dissertation, and what will it add to your writing?
• Try to break your research question(s) down into component parts. Then, map out where your literature review will need to provide extensive detail and where it can instead present quicker background. Allocate your research time and effort accordingly. 

Omitting dissenting views or findings

While reviewing the literature, you might discover authors who disagree with your central argument or whose own findings contradict your hypothesis. Don't omit those sources: embrace them! Remember, the literature review aims to explore the academic dialogue around your topic: disagreements or conflicting findings are often part of that dialogue, and including them in your writing will create a sense of rich, critical engagement. In fact, highlighting any disagreements amongst scholars is a great way to emphasise the relevance of, and need for, your own research.

Miscalculating the scope

As shown in the funnel structure (see 'Structure' tab for more), a literature review often starts broadly and then narrows the dialogue as it progresses, ultimately bringing the reader to the dissertation's specific research topic (e.g. the funnel's narrowest point).

Within that structure, it's common for writers to miscalculate the scope required. They might open the literature review far too broadly, dedicating disproportionate space to developing background information or general theory; alternately, they might rush into the narrowest part of the discussion, failing to develop any sense of surrounding context or background, first.

It takes trial and error to determine the appropriate scope for your literature review. To help with this...

• Imagine your literature review subtopics cascading down a stairwell,  as in the illustration below.
• Place the broadest concepts on the highest steps, then narrow down to the most specific concepts on the lowest steps: the scope 'zooms in' as you move down the stairwell.
• Now, consider which step is the most logical starting place for your readers. Do they need to start all the way at the top, or should you 'zoom in'?

The illustration above shows a stairwell diagram of a dissertation that aims to analyse Stephen King's horror novel  The Stand  through the lens of a specific feminist literary theory.

• If the literature review began on one of the bottom two steps, this would feel rushed and inadequate. The writer needs to explore and define the relevant theoretical lens before they discuss how it has been applied by other scholars.
• If the literature review began on the very top step, this would feel comically broad in terms of scope: in this writing context, the reader doesn't require a detailed account of the entire history of feminism!

The third step, therefore, represents a promising starting point: not too narrow, not too broad.

The 'islands' structure

Above all else, a literature review needs to synthesize a range of sources   in a logical fashion. In this context, to  synthesize  means to bring together, connect, weave, and/or relate. A common mistake writers make is failing to conduct such synthesis, and instead discussing each source in isolation. This leads to a disconnected structure, with each source treated like its own little 'island'. The island approach works for very few projects.

Some writers end up with this island structure because they confuse the nature of the  literature review  with the nature of an annotated bibliography . The latter is a tool you can use to analyse and keep track of individual sources, and most annotated bibliographies will indeed be arranged in a source-by-source structure. That's fine for pre-writing and notetaking, but to structure the literature review, you need to think about connections and overlaps between sources rather than considering them as stand-alone works.

If you are struggling to forge connections between your sources, break down the process into tiny steps:

• e.g. Air pollution from wood-burning stoves in homes.
• e.g.  Bryant and Dao (2022) found that X% of small particle pollution in the United Kingdom can be attributed to the use of wood-burning stoves.
• e.g.  A study by Williams (2023) reinforced those findings, indicating that small particle pollution has...
• e.g.  However, Landers (2023) cautions that factor ABC and factor XYZ may contribute equally to poor air quality, suggesting that further research...

The above exercise is  not  meant to suggest that you can only write one sentence per source: you can write more than that, of course! The exercise is simply designed to help you start synthesizing the literature rather than giving each source the island treatment.

Q: I still don't get it - what's the point of a literature review?

A: Let's boil it down to three key points...

• The literature review provides a platform for you, as a scholar, to demonstrate your understanding of how your research area has evolved. By engaging with seminal texts or the most up-to-date findings in your field, you can situate your own research within the relevant academic context(s) or conversation(s).
• The literature review allows you to identify the research gap your project addresses: in other words, what you will add to discussions in your academic field.
• Finally, the literature review justifies the reason for your research. By exploring existing literature, you can highlight the relevance and purpose of your own research.

Q: What if I don't have a gap?

A:  It's normal to struggle with identifying a research gap. This can be particularly true if you are working in a highly saturated research area, broadly speaking: for example, if you are studying the links between nutrition and diabetes, or if you are studying Shakespeare.

The 'What to Avoid' tab explained that  miscalculating the scope  is a common mistake in literature reviews. If you are struggling to identify your gap, scope might be the culprit, particularly if you are working in a saturated field. Remember that the gap is the narrowest part of the funnel, the smallest nesting doll, the lowest step: this means your contribution in that giant academic conversation will need to be quite 'zoomed in':

This is not a valid gap →  Analysing Shakespeare's sonnets.

This might be a valid gap →  Conducting an ecocritical analysis of the visual motifs of Shakespeare's final five procreation sonnets (e.g. sonnets number thirteen to seventeen).

In the above example, the revised attempt to articulate a gap 'zooms in' by identifying a particular theoretical lens (e.g. ecocriticism), a specific convention to analyse (e.g. use of visual motifs), and a narrower object (e.g. five sonnets rather than all 150+). The field of Shakespeare studies might be crowded, but there is nonetheless room to make an original contribution.

Conversely, it might be difficult to identify the gap if you are working not in a saturated field, but in a brand new or niche research area. How can you situate your work within a relevant academic conversation if it seems like the 'conversation' is just you talking to yourself?

In these cases, rather than 'zooming in', you might find it helpful to 'zoom out'. If your topic is niche, think creatively about who will be interested in your results. Who would benefit from understanding your findings? Who could potentially apply them or build upon them? Thinking of this in interdisciplinary terms is helpful for some projects.

Tip:  Venn diagrams and mind maps are great ways to explore how  your research connects to, and diverges from, the existing literature.

Q: How many references should I use in my literature review?

A:  This question is risky to answer because the variations between individual projects and disciplines make it impossible to provide a universal answer. The fact is that one dissertation might have 50 more references than another, yet the two projects could be equally rigorous and successful in fulfilling their research aims.

With that warning in mind, let's consider a 'standard' dissertation of around 10K words. In that context, referencing 30 to 40 sources in your literature review tends to work well. Again, this is  not  a universally accurate rule, but a ballpark figure for you to contemplate. If the 30 to 40 estimate seems frighteningly high to you, do remember that many sources will be used sparingly rather than being mulled over at length. Consider this example:

In British GP practices, pharmaceutical treatment is most often prescribed for Health Condition XYZ ( Carlos, 2019; Jones, 2020 ; Li, 2022 ). Lifestyle modifications, such as physical exercise or meditation practices, have only recently...

When writing critically, it's important to validate findings across studies rather than trusting only one source. Therefore, this writer has cited three recent studies that agree about the claim being made. The writer will delve into other sources at more length, but here, it makes sense to cite the literature and move quickly along.

As you search the databases and start following the relevant trails of 'research bread crumbs', you will be surprised how quickly your reference list grows.

Q: What if there isn't enough relevant literature on my topic?

A: Think creatively about the literature you are using and engaging with. A good start is panning out to consider your topic more broadly: you might not identify articles that discuss your  exact  topic, but what can you discover if you shift your focus up one level?

Imagine, for example, that Norah is researching how artificial intelligence (AI) can be used to provide dance instruction. She discovers that no one has written about this topic. Rather than panicking, she breaks down her research question into its component parts to consider what research  might  exist.

• First, dance instruction: literature on how dance has traditionally been taught (i.e., not with AI) is still relevant because it will provide background and context. To appreciate the challenges or opportunities that transition to AI instruction might bring, we need to understand the status quo. Norah might also search for articles that analyse how other technological shifts have affected dance instruction: for example, how YouTube popularized at-home dance study, or how live video services like Zoom enabled real-time interaction between dance pupils and teachers despite physical distance.
• Next, artificial intelligence used for instruction: Norah can seek out research on, and examples of, the application of AI for instructive purposes. Even if those purposes don't involve dance, such literature can contribute to illustrating the broader context around Norah's project.
• Could it be relevant to discuss the technologies used to track an actor's real-life movements and convert them into the motions of a video game character? Perhaps there are parallels!
• Could it be relevant to explore research on applications of AI in creative writing and visual art? Could be relevant since dance is also a creative field!

In summary, don't panic if you can't find research on your  exact  question or topic. Think through the broader context and parallel ideas, and you will soon find what you need.

Q: What if my discipline doesn't require a literature review chapter?

A: This is a great question. Whilst many disciplines dictate that your dissertation should include a chapter called Literature Review , not all subjects follow this convention. Those subjects will still expect you to incorporate a range of external literature, but you will nest the sources under different headings.

For example, some disciplines dictate an introductory chapter that is longer than average, and you essentially nest a miniature literature review inside the introduction, itself. Although the writing is more condensed and falls under a subheading of the introduction, the techniques and principles of writing a literature review (for example, moving from the broad to the narrow) will still prove relevant.

Some disciplines include chapters with names like Background , History , Theoretical Framework , etc. The exact functions of such chapters differ, but they have this in common: reviewing literature. You can't provide a critical background or history without synthesizing external sources. To illustrate your theoretical framework, you need to synthesize a range of literature that defines the theory or theories you intend to use.

Therefore, as stated earlier in this guide, you should be prepared to review and synthesize a range of literature regardless of your discipline. You can tailor the purpose of that synthesis to the structure and demands of writing in your subject area.

Q: Does my literature review need to include every source I plan to use in my discussion chapter?

A: The short answer is 'no' - there are some situations in which it is okay to use a source in your discussion chapter that you didn't integrate into your literature review chapter.

Imagine, for example, that your study produced a surprising result: a finding that you didn't anticipate. To make sense of that result, you might need to conduct additional research. That new research will help you explain the unexpected result in your discussion chapter.

More often, however, your discussion will  draw on, or return to, sources from your literature review. After all, the literature review is where you paint a detailed picture of the conversation surrounding your research topic. Thus, it makes sense for you to relate your own work to that conversation in the discussion.

The literature review provides you an opportunity to engage with a rich range of published work and, perhaps for the first time, critically consider how your own research fits within and responds to your academic community. This can be a very invigorating process!

At the same time, it's likely that you will be juggling more academic sources than you have ever used in a single writing project. Additionally, you will need to think strategically about the focus and scope of your work: figuring out the best structure for your literature review might require several rounds of re-drafting and significant edits.

If you are usually a 'dive in without a plan and just get drafting' kind of writer, be prepared to modify your approach if you start to feel overwhelmed. Mind mapping, organising your ideas on a marker board, or creating a bullet-pointed reverse outline can help if you start to feel lost.

Alternately, if you are usually a 'create a strict, detailed outline and stick to it at all costs' kind of writer, keep in mind that long-form writing often calls for writers to modify their plans for content and structure as their work progresses and evolves. It can help such writers to schedule periodic 'audits' of their outlines, with the aim being to assess what is still working and what else needs to be added, deleted or modified.

Here’s a final checklist for writing your literature review. Remember that not all of these points will be relevant for your literature review, so make sure you cover whatever’s appropriate for your dissertation. The asterisk (*) indicates any content that might not be relevant for your dissertation. You can save your own copy of the checklist to edit using the Word document, below.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How to write a literature review

Are you writing a literature review as part of a final year project, dissertation, or thesis, or as a standalone piece of work? This page will work through a process of organising and synthesising your sources and then writing a clear and critical final review.

What is a literature review?

A literature review is an account of the current thinking in a specific area of study. Its purpose is to introduce the reader to what has gone before and often to provide you with a foundation that you can build on with your own research. This traditional form of review is sometimes also referred to as a narrative review.

A literature review will often form a section or chapter of a larger piece of research work, such as a dissertation, thesis, or final year project.  It can also be a standalone piece of work.  

A literature review will usually do some or all of the following:

• Introduce the reader to a specific area of interest.
• Organise relevant sources thematically, starting with the more general, broader themes and narrowing towards the most specific themes.
• Introduce key theories relevant to the area of study.
• Define your understanding of important terms or language used in the research.
• Include only the most relevant, important or influential sources, carefully selected. It is about quality not quantity!
• Identify gaps or limitations in existing research.

Considering a body of scholarship as a whole (or in relation to each of your themes) will allow you to 'synthesise' multiple sources and produce an overall summary.

Developing a literature review will help you to develop a level of expertise in your chosen area. By consulting and including a unique combination of sources, you will be able to formulate an informed and original perspective.  Where relevant, this can drive forward your ongoing research.

A systematic review is a research methodology, often following a standardised and replicable search method and reporting structure that is specific to your discipline. Visit our guidance on systematic reviews for more information.

Organising your sources

As you encounter more and more relevant sources, you will face an ever-expanding amount of reading for yourself. It would take years to read through all of the literature in a specific field from start to finish.

Academic reading, and particularly the process of 'reading around' a topic, is about selective, or targeted reading. Visit our Reading and understanding information Hub to explore approaches to reading for different purposes.

Creating a Literature Matrix can help you to identify the key things that you want to take away from each source. A literature matrix is a simple spreadsheet where you select column titles to suit the aims of your literature review. Are you interested in the research methodology, the scale of the research, the main conclusions, or something else entirely?

Once you have scanned through a source and pulled out the points you are interested in, you can move onto the next source. Organising your reading in this way will also allow you to identify key themes that are emerging in your reading, which you will be able to use later on to plan your review.

You may want to use a reference management tool to help organise and produce your bibliography. Visit the University of Sheffield Library Reference Management pages here .

Make a copy of our Literature matrix template (Google Sheet) and add/delete columns based on the information you want to collect during your search.  Using a spreadsheet means that you can filter and sort your sources, for example, into chronological order, or alphabetically by author.

This downloadable example literature matrix shows how you can lay out your columns.

Synthesising your sources

Once you have a number of sources to work with, you will start to identify key themes emerging. At this point you can start to organise your sources systematically to develop and explore those themes. Can you organise your themes from the broadest to the narrowest and most specific?

A synthesis matrix will help you to identify a thematic structure for your literature review and to understand how the sources that you have found relate to one another. A synthesis matrix is a further spreadsheet that organises your sources by theme and includes a synthesis column, where you can begin to draw out comparisons between the sources. 

Once you have identified a number of sources for each theme in your matrix, you should be able to identify the following:

• Do the sources build on or develop one another? This may be a chronological process.
• Do the sources challenge or contradict one another? Do they reveal a debate within the field?
• Do the sources identify an area of particular interest or a gap in the field?
• Do the sources help to fill in gaps or complete a bigger picture?

Your synthesis column provides an opportunity for you to comment on multiple sources considered as a whole. It is a space for your critical voice and interpretation, which is a key part of writing a successful literature review.

Make a copy of our synthesis matrix (Google Sheet) to organise your themes and plan how the relevant sources can be synthesised.

Visit our Producing a literature review interactive tutorial - for further guidance.

Writing your review

Once you have done the background reading and organised your sources using a synthesis matrix, the job of writing your review is simply about adding flesh to the bones. You will need to write your review as a narrative account, but you can use your matrix as a framework to help you do so.

A literature review will usually follow a simple structure:

• Introduction: what is the overall topic area and how have you broken your review down into themes?
• Theme 1: the broadest, most top-level area (perhaps including some background theory that may have influenced your thinking).
• Theme 2, theme 3, theme 4, etc. Your themes should get progressively more specific and closer to the focus of your research.
• Conclusion: how has this informed your thinking and (if the review is part of a bigger project) what are your research aims and objectives? 

Your review may be broken down by section headings or be a continuous flow with themes clearly separated in a paragraph structure. Each section or paragraph will describe that theme and finish by summarising your overview of a theme (the synthesis part of the matrix above, which includes your critical analysis). 

Our web page How to structure a paragrap h has further guidance to ensure your paragraphs are clear and contain your synthesis and critical analysis.

Are you tired of hearing the phrase 'literature review' every five minutes at university and having no idea what it means, let alone where to start? Not to worry - we've got you covered with this step-by-step guide to creating a great dissertation literature review.

What is a literature review?

In short, a dissertation literature review provides a critical assessment of the sources (literature) you have gathered and read surrounding your subject area, and then identifies a “gap” in that literature that your research will attempt to address.

There are a lot of misunderstandings about what exactly a dissertation literature review entails, as it can vary. Whilst in some cases a dissertation literature review can be a simple summary of important sources, most often it requires you to critically engage with the text to convey your positive or negative opinions of it. What is your interpretation of a particular source? Does this interpretation differ considerably from other viewpoints in the literature? This is the sort of critical engagement expected from you in a literature review.

Whereas a summary will most likely provide a simple recap of the general arguments of the source(s), the expectations concerning a literature review extend beyond this. A literature review may provide a new perspective on a classic research paper or it may combine both new and old interpretations (this is the “gap” – more on this later). A literature review may also provide a thorough and critical outline of the intellectual developments in a field with a focus on major, and often polemical, debates. In other scenarios, a literature review may also provide an assessment of a source and inform a reader about its validity, pertinence and relevance to the research subject.

"In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”."

There tends to be confusion between literature reviews and academic papers in general, but they are not one and the same. Generally, academic papers aim to provide new research material about a particular subject, and a literature review features as part of this objective. In a research paper, the literature review forms the basis of the research – it helps to highlight any research gaps as support for a new argument or insights you intend to provide. In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”.

Is a literature review really necessary?

Now that we know what a literature review is, the next step is to understand the point of writing one in the first place. Like it or not, a literature review is an essential part of any academic piece of writing, as it demonstrates to your tutor or reader that you have a nuanced understanding of the sources concerning your research area or question.

Although it may seem arbitrary, the literature review helps to persuade the person reading and marking your assignment that what you have written about is relevant and your arguments are justified and worthwhile. So, in short, a literature review is essential, and you need to put the necessary time into getting it right.

How do you write a dissertation literature review?

As the next section of this blog is quite lengthy, we've broken it down into several key steps which should make it easier to follow when writing your own dissertation literature review. You start by identifying your sources, then you read and re-read them. Next, you think about any gaps in the research or literature you have used, and finally, you write your review using all the preparation and information gathered in the steps prior.

Identify sources

To write a good dissertation literature review, you need to have a fair idea of what sources you would like to review. If you haven’t been given a formal reference list by your tutor, refer back to the techniques we recommended earlier.

Make sure that your sources are balanced; include enough books and academic journals and any useful published work from reputable scholars. To help you choose your sources appropriately, you might want to think about the parameters and objectives of your research. What are you hoping to find out? In your literature review , what theoretical issues or perspectives do you aim to tackle? How about your methodology? Will you focus on mainly qualitative or quantitative studies, or a mixture of both? These general questions should help guide you in selecting your sources and again, remember that the abstract of a source is a very useful tool. Having a quick scan of the abstract and its ‘keywords’ will often give you an indication of the whether the source will be useful for your research or not.

As you’re identifying your sources, ensure you a keep a list as it’s very easy to lose focus given the wide scope of the Internet. Reference tools such as Mendeley allow you to store your sources online and via a desktop app, and are a great way to keep your bibliography organised. The citation tools attached to these programmes will also allow you to simply export citations in a format of your choice when required later. They will save you countless hours trying to figure out how to use Harvard or APA referencing correctly.

Read your sources

Now that you have organised your sources efficiently, it’s time to read through them. As unnatural as it may feel, it’s most effective to read in a few stages, as detailed below:

First, go through all the texts to get a sense of their general content and arguments. This will also help you judge which sources you mainly want to focus on in your review. During the second stage of your reading, you can then take a more critical, in-depth look at your sources. Make a lot of notes, be critical, ask questions. What is your academic opinion on the text? Do you have any comments on the methodological approach, the theoretical argument or the general hypothesis? Note these down. It will ensure that your literature review is not merely a summary of your readings, and will encourage a clear line of argument so that your work is logical and coherent.

Consider gaps in the research

When writing a dissertation literature review, an essential thing to consider is identifying the research gap. Identifying the gap is particularly important if your review forms part of a research proposal, as it will highlight the pertinence of your research – assuming that your research has been designed to fill this gap. In other instances, identifying the gap is an indication of good critical analysis and can score you extra points.

To identify the “gap” it is important that we know what this “gap” is. A research gap is essentially the existence of a research question, perspective or problem that has not been answered in the existing literature on any field of study. Identifying the research gap is important for highlighting the originality of your research; it proves you’re not simply recounting or regurgitating existing research. It also shows that you are very much aware of the status of the literature in your chosen field of study, which in turn, demonstrates the amount of research and effort you have put into your review.

Many students, especially at post-graduate level, find it extremely difficult to identify research gaps in their subject area. For post-graduate research papers, identifying research gaps and formulating research questions that can address these gaps form the very essence of a research paper. Identifying research gaps does not have to be a difficult endeavour and there are several ways to overcome this difficulty:

Start by reading A simple approach will be to read important parts of key articles in your research area. First, note that you’ll have to sift through many articles to identify the ones that are most suitable for your research. A quick search using keywords on Google Scholar will often give you a quick overview of the available literature. Other useful sources include databases such as JSTOR or Wiley Online Library . You can then snowball additional articles by clicking on ‘related articles’ or checking out which other papers have cited your source.

Abstracts and recommendations Whichever avenue you choose, reading the abstract is often a good starting point to get a sense of what the articles entails. You should also do a quick examination of the introductory and concluding paragraphs of the paper as these sections always provide some information on the aims and outcomes of the research, as well as ‘recommendations for future studies.’ These recommendations typically provide some insight on the research gaps in the literature. Another route would be to simply read as much as you can on your research subject while considering which research areas still need addressing in the literature – this is usually an indication of research gaps.

Write your review

Now you’re well prepared to start putting fingers to keyboard. Consider the following pointers:

1. Use sample literature reviews Have a look at sample dissertation literature reviews in your subject area and read them thoroughly to familiarise yourself with existing key debates and themes. This can be a good starting point for framing and structuring your own review. If you are not familiar with academic writing, going through samples will help you to get a sense of what is expected in this regard. Pay attention to the academic language and formal style used. Also, remember that the bibliography or reference section of your selected texts will help you to snowball further references if you need any.

2. Keep it simple Keep your topic as narrowed down as possible. Remember that there are hundreds – or in some instances, thousands – of sources or perspectives concerning any subject area or topic. Researchers investigate research problems in many divergent ways and the literature available on any given subject is extremely broad. In your literature review, you won’t be expected to address every argument or perspective concerning your topic – this might actually undermine your ability to write a coherent and focused piece. You’ll make your work easier if you limit the scope of your work. In your review, ensure that you clearly state what the focus of your work will be.

3. Make sure your sources are as current as possible If you are reviewing scientific work, it’s essential your sources are as current as possible given the advancements in the field over the years. In the medical field particularly, research is constantly evolving and a source that’s only three years old may be even out-dated. In the social sciences this rule may not apply, as many theoretical works are classics and you will be expected to be familiar with these perspectives. You might have to the review the work of Marx, or Hobbes, or any other classic scholar. You still need to balance theory with current approaches, as you will need to demonstrate the ways in which perspectives in the literature have changed over the years, or you may even want to demonstrate how scholars have used classic theories to inform their work.

4. Consider the organisation of your work In a dissertation literature review, organising your work goes beyond having an introduction, body and conclusion. You’ll be reviewing a number of texts, so you’ll also have to think clearly about how to organise themes, topics and your argument in general. Below is a detailed guide on how to do this:

Like any other academic paper, a dissertation literature review will comprise a basic introduction, body, and conclusion.

The introduction of a literature review should be clear, short and focused. It should outline the focus of the review – in other words, it should clearly state the main topics to be covered. A good literature review will also state the arguments to be made, as well as underlying rationale that underpins these arguments.

The body of your literature review will include an in-depth discussion of the academic sources you have chosen to review. You may choose to organise your sources according to themes, methodology or even based on a chronological order. In the body of your review, ensure that your arguments are presented clearly and that you link these arguments with the literature. Is there a scholar that agrees with your view? Say so, in a way that the reader will understand easily. This demonstrates that you are very familiar with the academic research in your field. Remember to also make note of any views that do not agree with your position; excluding these arguments will reduce the methodological robustness of your piece. You can use direct quotations in your literature review, however do so sparingly so you don’t appear lazy. Most tutors will not approach it kindly; the purpose of a literature review is to demonstrate your ability to critically engage with a piece of text, and littering your review with direct quotes isn’t a good indication of this. Instead, try to paraphrase quotations and only use direct quotes if it really helps to illustrate your argument.

In the summary of your dissertation literature review, it’s important to give a summary of the conclusions you’ve drawn from your readings. If your literature review forms part of a broader research proposal, reiterate the gaps in the literature here, and clearly state how your proposed research will fill these gaps. Make recommendations for future research in this section too, which demonstrates your analytical skills and will score you some extra points.

You now have the basic structure of your research in place, however it’s worth dedicating some time to what the body of your work should entail. The body is the main core of your work, so it’s important to consider how you will frame and organise it. You have options here – you can choose to organise the content of your work based on a chronological method, based on themes, trends or methodology, or based on arguments.

To structure the body of work chronologically, you will have to organise your sources based on when they were published. A limitation of this approach is that it inhibits continuity in your arguments and in some instances, can undermine the coherence of your work. Use with caution.

A more coherent way of organising your work is to group your sources based on the arguments they make in a ‘for versus against’ manner. This enables you to present your work in a more dynamic way and what’s more, makes the key debates in the literature more obvious. Say you were trying to convey the debates on European migration policy, you might want to start by writing something along these lines:

"While scholars such as X argue that migration policies must be made more stringent to counteract the increased flow of Syrian refugees to Europe, other scholars such as Y offer a divergent perspective. They specifically espouse a perspective based on a human rights approach…"

This approach also leaves room for you to insert your voice into the literature. Consider this statement:

"While X argues for the enactment of more stringent migration policies, this paper argues along the lines of Y that migration policies should be based on human rights considerations."

Using this technique also allows you to introduce additional literature that supports your position.

Another way of organising your content is according to theme; or sub-themes, if your review focuses on one overarching topic. This method of organisation still allows you to present an overview of any polemical debates within these sub-themes. A thematic review can easily shift between chronological periods within each sub-section too.

Structuring work using a methodological approach is quite a common approach, however it’s often used in tandem with other ways of organising sources. This method is particularly evident in introductory sections whereby researchers may simply want to state that a particular subject has been mostly studied from a qualitative or quantitative perspective (they will often then cite a number of scholars or studies to support this claim). In scientific reviews however, a methodological approach may form the basis of the discussions in the body. If this is the case for you, focus on the methods used by various researchers. How did they go about answering a particular research question? Were there any limitations to this method? If so, what method(s) would have been better?

You’ll soon realise that organising the body of your literature review is an iterative process and you’ll more often than not use all of these approaches in your write-up. The body of your research may also include additional sections that do not necessarily form a part of its organisational structure. For instance, you might want to include a ‘context section’ that provides some insight on any background detail required for understanding the focus of the literature review. It may also focus on historical considerations. You could include a short methodology section that details the approach you used in selecting and analysing your sources.

5. Write the paragraphs of the body Once you have settled on the approach to writing your body, you must now write each of its paragraphs in a way that is in keeping with academic conventions. Consider this paragraph from a literature review about stakeholder participation for environmental management, to clarify the discussion that follows:

Despite the rhetoric and the concerns that have been expressed, there have been few attempts to investigate the validity of the many claims that have been made for stake-holder participation (Webler, 1999; Beierle, 2002; Brody, 2003; Blackstock et al., 2007). The few attempts that have been made have tended to focus on evaluating the process rather than the outcomes (e.g. Beierle, 2002; Renn et al., 1995; Rowe and Frewer, 2000). This may be partly due to the challenge of selecting appropriate evaluation criteria and data collection methods. Blackstock et al., 2007 argue that the evaluation of participatory processes should itself be participatory, with stakeholders selecting and applying the evaluation criteria. However, this is not straightforward. Webler and Tuler (2006) found strong differences of opinion between participants that they selected from ten case studies, about what constituted a "good" participatory process. (Source: Reed, M.S., 2008. Stakeholder participation for environmental management: a literature review. Biological conservation, 141(10), pp.2417-2431).

As the example above suggests, a dissertation literature review must be written using a formal and academic style . Also, note how sources have been grouped according to both arguments and themes. Remember we noted that the process of grouping sources in the body of your literature review is never a linear one? You will often use a combination of the approaches that we have discussed. Ensure that your writing is concise, coherent and devoid of any personal or strong language. Avoid any phrases like, “I hate X’s work”; a more academic way of stating your disagreement would be to simply state: “I would argue against X’s position that…”, or “X’s argument is inconsistent with the evidence because...”, or “X’s arguments are based on false assumptions because...”.

In the sample paragraph above, notice the use of words like “argue” – this is a good academic alternative to more commonplace words such as “says”. Other good alternatives include “states”, “asserts”, “proposes” or “claims”. More academic options include “opine”, “posit”, “postulate”, or “promulgate”, however some tutors and readers find these words to be too ‘heavy’ and archaic, so ensure that you are familiar with the writing standards in your institution.

If your writing is tailored to a peer-reviewed journal, it’s worth having a look at articles within that journal to get a sense of the writing style. Most tutors will provide a guideline on writing styles, and it’s important you adhere to this brief. You will often be required to also use the third person when writing a literature review, thus phrases such as “this paper argues” or “this paper is of the view that…” are appropriate.

There are exceptions at post-graduate level or generally – like when you have conducted your own primary research or published your work widely – which give you the academic authority to boldly make claims. In cases like these, the use of first person is suitable and you may use phrases such as “I argue” or “I propose”.

Remember also to generally use present tense when referring to opinions and theories (although in the context of specific research experiments, the use of the past tense is better).

Beyond the use of the academic terms suggested above, ‘linking’ words are also particularly important when writing a literature review, since you’ll be grouping a lot of writers together with either similar or divergent opinions. Useful linking words and phrases include: similarly, there are parallels, in convergence with…

When there is disagreement, you may want to use any of the following: However, conversely, on the other hand, diverges from, antithetical to, differential from…

6. Write the conclusion The conclusion of a dissertation literature review should always include a summary of the implications of the literature, which you should then link to your argument or general research question.

Some final notes

The overall structure of your literature review will be largely based on your research area and the academic conventions that are in line with it. Nevertheless, there are some essential steps that apply across all disciplines and that you should ensure you follow:

Do not simply describe the opinions of writers Analyse, analyse, analyse, and ensure that your analysis is critical (what have the writers missed; where does your opinion sit with theirs, etc.).

Structure the body of your argument using various techniques Your structure should be organised based on thematic areas, key debates or controversial issues, and according to methodological approaches. Keep your review dynamic, but coherent. Remember to identify literature gaps and link this to your own research.

Use ample evidence This is extremely important and forms the very essence of a dissertation literature review. You must refer to various sources when making a point; see the sample paragraph above for an example of this. Your arguments and interpretation of a research topic must be backed by evidence. Do not make baseless claims, as a literature review is an academic piece of writing and not an opinion piece.

Be very selective Not every piece of research has to be reviewed. If you are determined to show that you aware of the available literature out there, try writing techniques such as: There is robust literature available concerning the migration patterns of Syrian refugees. Notable works include: X(2015), y (2013), Z (2014). Once you have acknowledged these works, you do not have to review them in detail. Be selective about the sources that you will discuss in detail in your review.

Do not rely too much on direct quotes Only use them to emphasise a point. Similarly, don’t rely too heavily on the work of a single author. Instead, highlight the importance of that author in your research and move on. If you need to keep going back to the work of that author, then you need to link those discussions with your work. Do not simply provide a summary of the author’s work. In what ways does your work agree or disagree with his/hers? Be critical.

Make your voice heard Yes, the whole point of the literature review is to provide a critical analysis and summary of the viewpoints out there, but a critical analysis does include the fact that you need to make your opinion known in the context of the literature. Note how skilfully, in the earlier sample paragraph by Reed (2008), he weaves his opinions with references. Read back over the sample and try to perfect this skill.

Ensure that you reference your work correctly And make sure you use the appropriate referencing style. For more help on this, click here .

How To Write A Dissertation Or Thesis

8 straightforward steps to craft an a-grade dissertation.

By: Derek Jansen (MBA) Expert Reviewed By: Dr Eunice Rautenbach | June 2020

Writing a dissertation or thesis is not a simple task. It takes time, energy and a lot of will power to get you across the finish line. It’s not easy – but it doesn’t necessarily need to be a painful process. If you understand the big-picture process of how to write a dissertation or thesis, your research journey will be a lot smoother.  

In this post, I’m going to outline the big-picture process of how to write a high-quality dissertation or thesis, without losing your mind along the way. If you’re just starting your research, this post is perfect for you. Alternatively, if you’ve already submitted your proposal, this article which covers how to structure a dissertation might be more helpful.

How To Write A Dissertation: 8 Steps

• Clearly understand what a dissertation (or thesis) is
• Find a unique and valuable research topic
• Craft a convincing research proposal
• Write up a strong introduction chapter
• Review the existing literature and compile a literature review
• Design a rigorous research strategy and undertake your own research
• Present the findings of your research
• Draw a conclusion and discuss the implications

Step 1: Understand exactly what a dissertation is

This probably sounds like a no-brainer, but all too often, students come to us for help with their research and the underlying issue is that they don’t fully understand what a dissertation (or thesis) actually is.

So, what is a dissertation?

At its simplest, a dissertation or thesis is a formal piece of research , reflecting the standard research process . But what is the standard research process, you ask? The research process involves 4 key steps:

• Ask a very specific, well-articulated question (s) (your research topic)
• See what other researchers have said about it (if they’ve already answered it)
• If they haven’t answered it adequately, undertake your own data collection and analysis in a scientifically rigorous fashion
• Answer your original question(s), based on your analysis findings

In short, the research process is simply about asking and answering questions in a systematic fashion . This probably sounds pretty obvious, but people often think they’ve done “research”, when in fact what they have done is:

• Started with a vague, poorly articulated question
• Not taken the time to see what research has already been done regarding the question
• Collected data and opinions that support their gut and undertaken a flimsy analysis
• Drawn a shaky conclusion, based on that analysis

If you want to see the perfect example of this in action, look out for the next Facebook post where someone claims they’ve done “research”… All too often, people consider reading a few blog posts to constitute research. Its no surprise then that what they end up with is an opinion piece, not research. Okay, okay – I’ll climb off my soapbox now.

The key takeaway here is that a dissertation (or thesis) is a formal piece of research, reflecting the research process. It’s not an opinion piece , nor a place to push your agenda or try to convince someone of your position. Writing a good dissertation involves asking a question and taking a systematic, rigorous approach to answering it.

If you understand this and are comfortable leaving your opinions or preconceived ideas at the door, you’re already off to a good start!

Step 2: Find a unique, valuable research topic

As we saw, the first step of the research process is to ask a specific, well-articulated question. In other words, you need to find a research topic that asks a specific question or set of questions (these are called research questions ). Sounds easy enough, right? All you’ve got to do is identify a question or two and you’ve got a winning research topic. Well, not quite…

A good dissertation or thesis topic has a few important attributes. Specifically, a solid research topic should be:

Let’s take a closer look at these:

Attribute #1: Clear

Your research topic needs to be crystal clear about what you’re planning to research, what you want to know, and within what context. There shouldn’t be any ambiguity or vagueness about what you’ll research.

Here’s an example of a clearly articulated research topic:

An analysis of consumer-based factors influencing organisational trust in British low-cost online equity brokerage firms.

As you can see in the example, its crystal clear what will be analysed (factors impacting organisational trust), amongst who (consumers) and in what context (British low-cost equity brokerage firms, based online).

Need a helping hand?

Attribute #2:   Unique

Your research should be asking a question(s) that hasn’t been asked before, or that hasn’t been asked in a specific context (for example, in a specific country or industry).

For example, sticking organisational trust topic above, it’s quite likely that organisational trust factors in the UK have been investigated before, but the context (online low-cost equity brokerages) could make this research unique. Therefore, the context makes this research original.

One caveat when using context as the basis for originality – you need to have a good reason to suspect that your findings in this context might be different from the existing research – otherwise, there’s no reason to warrant researching it.

Attribute #3: Important

Simply asking a unique or original question is not enough – the question needs to create value. In other words, successfully answering your research questions should provide some value to the field of research or the industry. You can’t research something just to satisfy your curiosity. It needs to make some form of contribution either to research or industry.

For example, researching the factors influencing consumer trust would create value by enabling businesses to tailor their operations and marketing to leverage factors that promote trust. In other words, it would have a clear benefit to industry.

So, how do you go about finding a unique and valuable research topic? We explain that in detail in this video post – How To Find A Research Topic . Yeah, we’ve got you covered 😊

Step 3: Write a convincing research proposal

Once you’ve pinned down a high-quality research topic, the next step is to convince your university to let you research it. No matter how awesome you think your topic is, it still needs to get the rubber stamp before you can move forward with your research. The research proposal is the tool you’ll use for this job.

So, what’s in a research proposal?

The main “job” of a research proposal is to convince your university, advisor or committee that your research topic is worthy of approval. But convince them of what? Well, this varies from university to university, but generally, they want to see that:

• You have a clearly articulated, unique and important topic (this might sound familiar…)
• You’ve done some initial reading of the existing literature relevant to your topic (i.e. a literature review)
• You have a provisional plan in terms of how you will collect data and analyse it (i.e. a methodology)

At the proposal stage, it’s (generally) not expected that you’ve extensively reviewed the existing literature , but you will need to show that you’ve done enough reading to identify a clear gap for original (unique) research. Similarly, they generally don’t expect that you have a rock-solid research methodology mapped out, but you should have an idea of whether you’ll be undertaking qualitative or quantitative analysis , and how you’ll collect your data (we’ll discuss this in more detail later).

Long story short – don’t stress about having every detail of your research meticulously thought out at the proposal stage – this will develop as you progress through your research. However, you do need to show that you’ve “done your homework” and that your research is worthy of approval .

So, how do you go about crafting a high-quality, convincing proposal? We cover that in detail in this video post – How To Write A Top-Class Research Proposal . We’ve also got a video walkthrough of two proposal examples here .

Step 4: Craft a strong introduction chapter

Once your proposal’s been approved, its time to get writing your actual dissertation or thesis! The good news is that if you put the time into crafting a high-quality proposal, you’ve already got a head start on your first three chapters – introduction, literature review and methodology – as you can use your proposal as the basis for these.

Handy sidenote – our free dissertation & thesis template is a great way to speed up your dissertation writing journey.

What’s the introduction chapter all about?

The purpose of the introduction chapter is to set the scene for your research (dare I say, to introduce it…) so that the reader understands what you’ll be researching and why it’s important. In other words, it covers the same ground as the research proposal in that it justifies your research topic.

What goes into the introduction chapter?

This can vary slightly between universities and degrees, but generally, the introduction chapter will include the following:

• A brief background to the study, explaining the overall area of research
• A problem statement , explaining what the problem is with the current state of research (in other words, where the knowledge gap exists)
• Your research questions – in other words, the specific questions your study will seek to answer (based on the knowledge gap)
• The significance of your study – in other words, why it’s important and how its findings will be useful in the world

As you can see, this all about explaining the “what” and the “why” of your research (as opposed to the “how”). So, your introduction chapter is basically the salesman of your study, “selling” your research to the first-time reader and (hopefully) getting them interested to read more.

How do I write the introduction chapter, you ask? We cover that in detail in this post .

Step 5: Undertake an in-depth literature review

As I mentioned earlier, you’ll need to do some initial review of the literature in Steps 2 and 3 to find your research gap and craft a convincing research proposal – but that’s just scratching the surface. Once you reach the literature review stage of your dissertation or thesis, you need to dig a lot deeper into the existing research and write up a comprehensive literature review chapter.

What’s the literature review all about?

There are two main stages in the literature review process:

Literature Review Step 1: Reading up

The first stage is for you to deep dive into the existing literature (journal articles, textbook chapters, industry reports, etc) to gain an in-depth understanding of the current state of research regarding your topic. While you don’t need to read every single article, you do need to ensure that you cover all literature that is related to your core research questions, and create a comprehensive catalogue of that literature , which you’ll use in the next step.

Reading and digesting all the relevant literature is a time consuming and intellectually demanding process. Many students underestimate just how much work goes into this step, so make sure that you allocate a good amount of time for this when planning out your research. Thankfully, there are ways to fast track the process – be sure to check out this article covering how to read journal articles quickly .

Literature Review Step 2: Writing up

Once you’ve worked through the literature and digested it all, you’ll need to write up your literature review chapter. Many students make the mistake of thinking that the literature review chapter is simply a summary of what other researchers have said. While this is partly true, a literature review is much more than just a summary. To pull off a good literature review chapter, you’ll need to achieve at least 3 things:

• You need to synthesise the existing research , not just summarise it. In other words, you need to show how different pieces of theory fit together, what’s agreed on by researchers, what’s not.
• You need to highlight a research gap that your research is going to fill. In other words, you’ve got to outline the problem so that your research topic can provide a solution.
• You need to use the existing research to inform your methodology and approach to your own research design. For example, you might use questions or Likert scales from previous studies in your your own survey design .

As you can see, a good literature review is more than just a summary of the published research. It’s the foundation on which your own research is built, so it deserves a lot of love and attention. Take the time to craft a comprehensive literature review with a suitable structure .

But, how do I actually write the literature review chapter, you ask? We cover that in detail in this video post .

Step 6: Carry out your own research

Once you’ve completed your literature review and have a sound understanding of the existing research, its time to develop your own research (finally!). You’ll design this research specifically so that you can find the answers to your unique research question.

There are two steps here – designing your research strategy and executing on it:

1 – Design your research strategy

The first step is to design your research strategy and craft a methodology chapter . I won’t get into the technicalities of the methodology chapter here, but in simple terms, this chapter is about explaining the “how” of your research. If you recall, the introduction and literature review chapters discussed the “what” and the “why”, so it makes sense that the next point to cover is the “how” –that’s what the methodology chapter is all about.

In this section, you’ll need to make firm decisions about your research design. This includes things like:

• Your research philosophy (e.g. positivism or interpretivism )
• Your overall methodology (e.g. qualitative , quantitative or mixed methods)
• Your data collection strategy (e.g. interviews , focus groups, surveys)
• Your data analysis strategy (e.g. content analysis , correlation analysis, regression)

If these words have got your head spinning, don’t worry! We’ll explain these in plain language in other posts. It’s not essential that you understand the intricacies of research design (yet!). The key takeaway here is that you’ll need to make decisions about how you’ll design your own research, and you’ll need to describe (and justify) your decisions in your methodology chapter.

2 – Execute: Collect and analyse your data

Once you’ve worked out your research design, you’ll put it into action and start collecting your data. This might mean undertaking interviews, hosting an online survey or any other data collection method. Data collection can take quite a bit of time (especially if you host in-person interviews), so be sure to factor sufficient time into your project plan for this. Oftentimes, things don’t go 100% to plan (for example, you don’t get as many survey responses as you hoped for), so bake a little extra time into your budget here.

Once you’ve collected your data, you’ll need to do some data preparation before you can sink your teeth into the analysis. For example:

• If you carry out interviews or focus groups, you’ll need to transcribe your audio data to text (i.e. a Word document).
• If you collect quantitative survey data, you’ll need to clean up your data and get it into the right format for whichever analysis software you use (for example, SPSS, R or STATA).

Once you’ve completed your data prep, you’ll undertake your analysis, using the techniques that you described in your methodology. Depending on what you find in your analysis, you might also do some additional forms of analysis that you hadn’t planned for. For example, you might see something in the data that raises new questions or that requires clarification with further analysis.

The type(s) of analysis that you’ll use depend entirely on the nature of your research and your research questions. For example:

• If your research if exploratory in nature, you’ll often use qualitative analysis techniques .
• If your research is confirmatory in nature, you’ll often use quantitative analysis techniques
• If your research involves a mix of both, you might use a mixed methods approach

Again, if these words have got your head spinning, don’t worry! We’ll explain these concepts and techniques in other posts. The key takeaway is simply that there’s no “one size fits all” for research design and methodology – it all depends on your topic, your research questions and your data. So, don’t be surprised if your study colleagues take a completely different approach to yours.

Step 7: Present your findings

Once you’ve completed your analysis, it’s time to present your findings (finally!). In a dissertation or thesis, you’ll typically present your findings in two chapters – the results chapter and the discussion chapter .

What’s the difference between the results chapter and the discussion chapter?

While these two chapters are similar, the results chapter generally just presents the processed data neatly and clearly without interpretation, while the discussion chapter explains the story the data are telling  – in other words, it provides your interpretation of the results.

For example, if you were researching the factors that influence consumer trust, you might have used a quantitative approach to identify the relationship between potential factors (e.g. perceived integrity and competence of the organisation) and consumer trust. In this case:

• Your results chapter would just present the results of the statistical tests. For example, correlation results or differences between groups. In other words, the processed numbers.
• Your discussion chapter would explain what the numbers mean in relation to your research question(s). For example, Factor 1 has a weak relationship with consumer trust, while Factor 2 has a strong relationship.

Depending on the university and degree, these two chapters (results and discussion) are sometimes merged into one , so be sure to check with your institution what their preference is. Regardless of the chapter structure, this section is about presenting the findings of your research in a clear, easy to understand fashion.

Importantly, your discussion here needs to link back to your research questions (which you outlined in the introduction or literature review chapter). In other words, it needs to answer the key questions you asked (or at least attempt to answer them).

For example, if we look at the sample research topic:

In this case, the discussion section would clearly outline which factors seem to have a noteworthy influence on organisational trust. By doing so, they are answering the overarching question and fulfilling the purpose of the research .

For more information about the results chapter , check out this post for qualitative studies and this post for quantitative studies .

Step 8: The Final Step Draw a conclusion and discuss the implications

Last but not least, you’ll need to wrap up your research with the conclusion chapter . In this chapter, you’ll bring your research full circle by highlighting the key findings of your study and explaining what the implications of these findings are.

What exactly are key findings? The key findings are those findings which directly relate to your original research questions and overall research objectives (which you discussed in your introduction chapter). The implications, on the other hand, explain what your findings mean for industry, or for research in your area.

Sticking with the consumer trust topic example, the conclusion might look something like this:

Key findings

This study set out to identify which factors influence consumer-based trust in British low-cost online equity brokerage firms. The results suggest that the following factors have a large impact on consumer trust:

While the following factors have a very limited impact on consumer trust:

Notably, within the 25-30 age groups, Factors E had a noticeably larger impact, which may be explained by…

Implications

The findings having noteworthy implications for British low-cost online equity brokers. Specifically:

The large impact of Factors X and Y implies that brokers need to consider….

The limited impact of Factor E implies that brokers need to…

As you can see, the conclusion chapter is basically explaining the “what” (what your study found) and the “so what?” (what the findings mean for the industry or research). This brings the study full circle and closes off the document.

Let’s recap – how to write a dissertation or thesis

You’re still with me? Impressive! I know that this post was a long one, but hopefully you’ve learnt a thing or two about how to write a dissertation or thesis, and are now better equipped to start your own research.

To recap, the 8 steps to writing a quality dissertation (or thesis) are as follows:

• Understand what a dissertation (or thesis) is – a research project that follows the research process.
• Find a unique (original) and important research topic
• Craft a convincing dissertation or thesis research proposal
• Write a clear, compelling introduction chapter
• Undertake a thorough review of the existing research and write up a literature review
• Undertake your own research
• Present and interpret your findings

Once you’ve wrapped up the core chapters, all that’s typically left is the abstract , reference list and appendices. As always, be sure to check with your university if they have any additional requirements in terms of structure or content.

Hello, your write ups is quite educative. However, l have challenges in going about my research questions which is below; *Building the enablers of organisational growth through effective governance and purposeful leadership.*

Very educating.

Just listening to the name of the dissertation makes the student nervous. As writing a top-quality dissertation is a difficult task as it is a lengthy topic, requires a lot of research and understanding and is usually around 10,000 to 15000 words. Sometimes due to studies, unbalanced workload or lack of research and writing skill students look for dissertation submission from professional writers.
