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.
Wrestling an elephant into a cupboard: how to write a PhD literature review in nine easy steps
Feb 10, 2019
When I was writing my PhD I hated the literature review. I was scared of it. One day, my supervisor took me to one side and told me that I had no choice: ‘It was going to have to be done before you start fieldwork’. I was terrified.
Sound familiar? According to Google, 5,000 people a month search for advice on how to conduct a literature review. And we know from the one-on-one PhD coaching we offer and from the theses we proofread that many students struggle with this part of their thesis.
If you’re feeling lost, keep reading. In this guide, I’ll walk you through the nine steps involved in conducting and writing a PhD literature review.
You’ll realise what I eventually found out: C onducting a literature review is easy. Okay, perhaps that’s a bit much. Let me rephrase: Conducting a PhD literature review isn’t as hard as you think.
What a PhD literature review isn’t
Let us make one thing very clear. A PhD literature review isn’t just a summary of existing literature. That’s an annotated bibliography and that isn’t what a PhD literature review is about. This is the mistake I see most frequently in the PhDs I proofread.
Not only will your examiners send this back for corrections, but it may mean the whole PhD thesis is problematic because it isn’t grounded in a critical review of the literature.
What a PhD literature review is
A PhD literature review is a critical assessment of the literature in your field and related to your specific research topic. When discussing each relevant piece of literature, the review must highlight where the gaps are and what the strengths and weaknesses are of particular studies, papers, books, etc. Also, different pieces of literature are compared and contrasted with one another so that themes and relationships are highlighted.
The job of a literature review is to show five things (if you’re using our PhD Writing Template , you may recognise these):
1. What has been written on your topic 2. Who the key authors are and what the key works are 3. The main theories and hypotheses 4. The main themes that exist in the literature 5. Gaps and weaknesses that your study will then help fill
Who cares what other people have written and said, or what they haven’t said? Well, you should and your examiners definitely will. For your own study to make sense, it has to be situated in the literature. That means you must relate it to what others are talking about.
If you wanted to build a new mobile phone, you would have to research how other mobile phones are built, find out where they can be improved and then design one that makes those improvements.
The literature review is the same.
But where do I start? Here, we list nine steps. Follow each and you’ll be on your way to literature review greatness.
We’ve made the infographic below to help you on your way. Click the image to download it.
Step One: Pick a Broad Topic
You will be reviewing literature on a particular topic, so knowing what your topic is beforehand means you can narrow down your search. At this stage your topic is broad. You won’t be able to know the specifics until you do the review itself.
For my PhD, which looked at the contributions that local government made to climate change policy, my literature review started with a broad topic of ‘climate change policy’. I didn’t focus in on local government until I had read the literature on climate change policy and realized there was a gap.
So, having a clearly defined purpose is really important. Otherwise you are searching blind. If you refer to your PhD Writing Template, take a look at the box titled ‘Aims & Objectives’ – you’ll need to make sure you have established your aims, scope and research questions.
Step Two: Find the Way In
If you search for your broad topic in Google Scholar, you’ll be presented with millions of results. With my own PhD, a search for ‘climate change policy’ bought up over 3 million results.
Obviously it’s unfeasible to read through all these.
So where do you start? Easy: choose the biggest names in your field.
There are three ways to find these:
1. Textbooks 2. Review articles 3. Most-cited articles
Read through these seminal texts and you’ll begin to get an idea of the broad topic.
Step Three: Who’s Saying What & When
Your job at this stage is to find out the key debates in the field.
- Who is making the most significant contribution?
- What are they saying?
- How are they saying it?
- What aren’t they saying?
Step Four: Notes, Notes, Notes.
Whenever you read anything you should be taking notes. Detailed notes. These need to cover the following points:
- What is the author saying?
- How is it relevant to your research?
- What are the gaps/weaknesses?
- What are the key references that you should read?
The more of these kind of standardised notes you have, the easier it will be when you write your literature review.
Step Five: Narrow Down the Field
As you read the key texts, you will begin to see what the key debates are in your field. There might be a number of ’schools’, for example. When you become aware of them, start to focus your literature review around them.
Step Six: Filter Through Your Growing List of References
Don’t just read everything. You need to find a way to filter through the articles or books that are relevant. For example, scan the abstracts, introduction, keywords, titles and references.
Filter the sources you come across into three separate categories:
- Probably won’t read
Step Seven: Use Snowball Sampling
As you read through these articles, look at their reference list. Collect articles that you think will be relevant and use them in your literature review. This is known as snowball sampling.
Step Eight: Think About the Questions that Haven’t Been Asked
You must be reading critically, which means asking what the weaknesses are and where particular articles or book could be improved.
In order to tease out your own specific research topic, you need to think of the questions that haven’t been asked.
Step Nine: Writing Up Your Literature Review
The review will broadly follow the key debates you have spotted in step five above. As you write, focus on putting in more detail about particular sources (i.e. flesh out steps six and seven). The focus when writing is to elaborate upon the key patterns and themes that have emerged.
However, you need to include your own synthesis of the material. I said earlier that you shouldn’t just summarize the literature. Instead you should write critically. You should clearly and precisely present your argument. The argument will focus around the questions that haven’t been asked – step nine above – and will ground the literature review. We’ve written a guide to being critical in your literature review . You should read it if you’re unsure what’s required.
So, write early and write that first draft quickly. The earlier you start writing your literature review the better. You must accept that your first draft is going to be just that: a draft. When you write the first draft, focus on the broad structure first. This means focus on the broad themes you want to discuss in the review.
Something you need to consider is how to structure the chapter. The simple answer is that you can either structure it chronologically or thematically.
The long answer is that chronological literature reviews are restrictive and over-simplify the field. They are useful for very early drafts of the review and can help you to arrange the literature and trace threads and connections within it. However, your supervisors and examiners are looking for thematic reviews (unless they have told you otherwise), where you discuss the literature with reference to the themes that have emerged.
Equally important is knowing when to stop reviewing the literature.
The sooner you go out and do your fieldwork, the better. The literature review is a cruel mistress; you’ll struggle to fully nail down its various components and fully understand how everything you have read is related. But don’t despair; aspects of the literature review will become clearer when you enter the field and start to collect data.
Don’t fall into the trap of spending too long in the library and too little time doing fieldwork.
It’s natural to be scared of the literature review. To conduct one, you have to read, process and synthesise hundreds of thousands of words. But it’s not impossible. Keep this guide to hand and refer to it when you feel yourself getting lost. Share it with your colleagues so they too can conquer their fear of the literature review.

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.

begin by clearing up some misconceptions about what a literature review is and what it is not. Then, I will break the process down into a series of simple steps, looking at examples along the way. In the end, I hope you will have a simple, practical strategy to write an effective literature review.
When you begin to write your PhD literature review, it’s important to have a clear idea of its outline. Roughly speaking, the literature review structure should: Introduce your topic and explain its significance; Evaluate the existing literature with reference to your thesis
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: Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.
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.
A PhD literature review is a critical assessment of the literature in your field and related to your specific research topic. When discussing each relevant piece of literature, the review must highlight where the gaps are and what the strengths and weaknesses are of particular studies, papers, books, etc.
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. Though technically Chapter 2 of your dissertation, many students write their literature review first. Why?
