Literature review doctoral thesis writing

In this post, I’m going to guide you through how to write a literature review on any topic from scratch, even if you haven’t read a single paper yet.

How to write a literature review from scratch

1. Pick a topic

It can be as broad as you like, because this is just a starting point. If you are still picking your specific topic for your PhD, that’s fine, but you should at least know roughly what area you want to explore.

2. Find your way in

A quick google scholar search for your subject area could turn up as many as 1 million results. Clearly you can’t read them all, so you need to look for an easy way in.

The vast majority of academic papers are written for people already familiar with the subject. They will refer to theories and methodologies assuming that the reader knows what they are.

So to start with just any paper at random would be a demoralizing waste of time, as you’ll be overwhelmed by the jargon. Instead, you need something you can understand easily to give yourself a foundation of knowledge to build upon.

Textbooks and review articles can be good places to start, though even these can be highly technical. If you can’t find one you can understand easily, then look for a book written for the general, non-academic public.

The idea is to gain a quick, broad background knowledge before getting into more specialised technical detail.

3. History, people ideas

The idea of a literature review is to give some background and context to your own work. You need to show how your research fits into the big picture, relating it to what has been done before.

You don’t need to write a comprehensive history of your subject, but it helps if you know roughly how it has developed over time.

So as you read a few general introductions to your topic, you’ll start to get an overview of the key ideas and theories, who developed them, and when.

Also note any conflicting ideas, any controversy or disagreement in the field, as you’ll need to know this kind of thing.

Now you can start to look for specific papers.

4. Find the world-changing literature

Once you know who the world changers were, you can go in search of their papers.

You need to make sure you understand these key concepts, as they will help you decipher other papers which built upon these ideas.

Sometimes, those world changing papers can be tough to read, but as long as you know roughly what they did and understand the key principle, that’s enough.

5. Get specific

Only once you have a grasp of the key ideas in your field should you get more specific.

There may be several angles you can take in your research, and you may have to explore many areas of the literature. So divide your literature search into sections to make it easier to manage. For each section, think of several keywords to try out in different combinations.

6. Filter

Even when you look at highly specialised sub-topics, there may still be thousands upon thousands of papers, so you need to filter them. Here are a few ways to reduce the numbers:

  • Look at the number of citations as an indication of quality
  • Make your keywords more specific
  • Scan the abstract and make a quick decision as to whether it will be relevant or not

Don’t be afraid to reject papers.

You can always come back to them later, but you have to start with something manageable.

7. Filter again

You might not be able to read everything in depth immediately. From the papers you selected, give them a ranking A, B, or C.

A = must read. highly relevant, high quality

B = unsure. probably relevant, but not yet sure how

C = probablyirrelevant. not what you thought it was when you read the title

If you’ve printed them. put the letter A, B, or C on the front so you can tell quickly when you come back to them (maybe months or years later)

8. Use other people’s bibliographies

Even if you can only find one good quality paper, read the introduction carefully and see who they cite. There may be a few gems there you didn’t find with the search engine.

Also see who else has cited that one paper since it was published (this is also a very quick way to update your bibliography if you are coming back to it a year or more later).

9. Get to know the big players

In any research field, no matter how specialised, there will be leading experts or competing research groups. Figure out who they are, and read their work.

10. Make sure your research idea is original

As the saying goes, you can’t prove a negative. How can you prove that nobody else has done what you plan to do, without searching every paper ever published?

Well, it’s worth spending a day or two searching every keyword combination you can think of related to your specific research plan.

11. Write about ideas

When you finally start writing your literature review, focus on ideas and use examples from the literature to illustrate them.

Don’t just write about every paper you have found (I call this the telephone-directory approach), as it will be tedious to write and impossible to read.

The aim should always be to cite the best and most relevant research, rather than going for sheer quantity.

12. Remember, you aren’t writing a textbook

So you can leave out big chunks. Write about what is relevant to your research.

13. Vary the detail

When talking about a broad topic, only cite the very, very best papers. You’ll have a lot to choose from. so why choose anything but the best?

Then when you get into more specialised sections, you can include a larger number of less well-known papers (but still the highest quality you can find).

14. Don’t cite anything&…

Don’t cite anything you haven’t read or don’t understand

15. Get experience

Your perspective on the literature will be quite different once you have done your own research. If you are in your first year, get your literature review done quickly so you can move on with your own work, and don’t let it hold you back.

It takes time to figure out what makes a good paper and what makes a bad one, and that comes with experience of carrying out research, talking to other researchers, and just reading more.

Reader Interactions


Clara Tang says

I am a first year PhD student in criminology at my proposal writing stage. I am of the view my literature review at this stage is just to familiarize myself with the key readings around my research how they relate to my expected findings and to demonstrate there is some degree of original contribution. My view is proposal allows the university, and my supervisor, to send me off into the field with some comfort I have thought about what I am going to do.

Most students are approaching this literature review in the proposal as a way to “finish a chapter early in their thesis”. I find this approach illogical, as how can you possibly know what your literature review will be about until you have completed your research? it seems massive waste of time when i could be collecting data in the field on my reserach. Am I being careless? Any thoughts would be welcomed.

James Hayton says

I agree, writing a lit review chapter at the start isn’t the best approach. After a few years working in the field you should be able to write a much better review at the end of your PhD, so even if you do write a chapter now it will inevitably need rewriting later.

That said, you should be able to provide some background and context to your proposal by referring to the existing literature.

Clara Tang says

Perfect. Thanks for keeping me sane.

Thank you for sharing all this info. I have a question related to reading for the Lit Review. I am trying to work in a systematic way with my PhD. I have have collected theses and scientific articles related to my topic. My question is: do I need to read the entire theses and articles or can I simply focus on the Abstract and conclusions?

James Hayton says

It’s not a question of one or the other- for particularly important sources, you may need to read them several times in great detail- others you may just skim read and some you might only read the abstract (though you shouldn’t cite anything you haven’t read beyond the abstract).

OK- got you. Thanks for your prompt reply.

When writing a Literature review do I need to write my personal thoughts in each paragraph? depending on what is written?

James Hayton says

Not in every paragraph, no. For example, you can say, &”since the theory of &… was first proposed by &… in &…, there has been extensive research into the effects of &…&” You don’t need to say what you think of it if it’s a quick summary of something everyone in the field already knows. It really depends whether you have personal thoughts you think are important to communicate in that particular paragraph.

Kaahwa Mark says

Hey James,
Thanks so much for all your brilliant ideas on research. I am a PhD student in my first year. Will read over and over again to grasp and internalize these ideas.
My question is how do I know that, I have reviewed enough literature and that is where I am supposed to stop?

James Hayton says

You never stop as long as you’re an academic&… but if you’re writing then there have to be some constraints. Some areas of the literature, it’s enough just to have a rough idea what’s going on, other areas you constantly need to stay up to date (keep an eye on your direct competitors).

Gail Hunter says

This was a very helpful guide. I charted about 50 articles by topic, year, journal, and author. And then I grouped about 20 by subtopic. This semester I will plow ahead writing how my ideas fit or differ from each if them. Then I’ll add about 15 more and voila! Connecting with some if the researchers on ResearchGate has been quite inspiring, I must say.

James Hayton says

I’m not sure I was clear enough in the blog post, as what you’ve described doesn’t sound like my method for lit reviews.

I’m also working on a corner of my field that hasn’t really been touched, but I’ve found that my research bridges the gap between two areas that have had significant work done in them. Maybe that would be a good place to start? If it were me, I’d figure out exactly where my research fits into the big picture, and then build a bridge between the nearest pieces of solid ground.

Nana Amoah says

Trust me! I am in the middle of writing my Literature review chapter and decided to just take a cursory look around to see what help I could get from anywhere&…..this Helped! It sure did!

Hi, although my research topic is quite specific, it draws on a massive amount of literature that has been thoroughly reviewed by a number of outstanding authors. My question is, would it be reasonable to take advantage of those reviews,(i.e. cite them) and concentrate my own lit review on those topics/articles that have built on their work?

Hi James, i realy liked the idea of categorising the literature.Very thanks

Categorizing articles to A, B, C and D is one great idea. I am going to do that because i have hundred of articles that i havent finished reading and do not know which to read first!

I think you have noted some very interesting points. appreciate it for the post. gdaegkakaccd

Hi, I’m writing my first lit review for an honors paper and I need so help clarifying a issue. Let’s say most studies looked at A and C, but in my study I want to look at what will happen if we look at B.
Now apart from sketching the background of your area etc. they say you should show and talk about where your research (B) fits into the picture and what you will be looking at.
Where in your lit review do you put this in, its own section or try to work it into various other sections? Do you talk in future tense about this or what?
Any help would be greatly appreciated.

Good suggestions! Great recommendation about rating the importance of articles as a way to filter through what may or may not be relevant&…simple concept but something i always grapple with.

Eleanor Skidmore says

How many papers should I research for my literature review? My tutor says I should have 30 references in my bibliography. but will I need to look at more?

If your tutor says 30, aim for about 30. If you think there are a few more you want to put in, put a few more in.

Go for quality and relevance, don’t worry about the number.

Primary Sidebar

In their book, Destination Dissertation: A Traveler’s Guide to a Done Dissertation , Sonja Foss and William Walters describe a highly efficient way of writing a literature review. I think it provides an excellent guide for getting through the massive amounts of literature for any purpose: in a doctorate program, for writing an M.A. thesis, or an article in any field of study.

Step One: Decide on your areas of research

Before you begin to search for articles or books, decide beforehand what areas you are going to research. Make sure that you only get articles and books in those areas, even if you come across fascinating books in other areas.

Step Two: Search for the literature:

Conduct a comprehensive bibliographic search of books and articles in your area. Read the abstracts online and download and/or print those articles that pertain to your area of research. Find books in the library that are relevant and check them out. Set a specific time frame for how long you will search. It should not take more than two or three dedicated time sessions.

Step Three: Find relevant excerpts in your books and articles:

Skim the contents of each book and article and look specifically for these five things:

  1. Claims, conclusions, and findings about the constructs you are investigating
  2. Definitions of terms
  3. Calls for follow-up studies relevant to your project
  4. Gaps you notice in the literature
  5. Disagreement about the constructs you are investigating

When you find any of these five things, type the relevant excerpt directly into a Word document. Don’t summarize, as summarizing takes longer than simply typing the excerpt. Make sure to note the name of the author and the page number following each excerpt. Do this for each article and book that you have in your stack of literature. When you are done, print out your excerpts.

Step Four: Code the literature

Get out a pair of scissors and cut each excerpt out. Now, sort the pieces of paper into similar topics. Figure out what the main themes. Place each excerpt into a themed pile. Make sure each note goes into a pile. If there are excerpts that you can’t figure out where they belong, separate those and go over them again at the end to see if you need new categories. When you finish, place each stack of notes into an envelope labeled with the name of the theme.

Step Five: Create Your Conceptual Schema

Type, in large font, the name of each of your coded themes. Print this out, and cut the titles into individual slips of paper. Take the slips of paper to a table or large workspace and figure out the best way to organize them. Are there ideas that go together or that are in dialogue with each other? Are there ideas that contradict each other? Move around the slips of paper until you come up with a way of organizing the codes that makes sense. Write the conceptual schema down before you forget or someone cleans up your slips of paper!

Step Six: Begin to Write Your Literature Review

Choose any section of your conceptual schema to begin with. You can begin anywhere, because you already know the order. Find the envelope with the excerpts in them and lay them on the table in front of you. Figure out a mini-conceptual schema based on that theme by grouping together those excerpts that say the same thing. Use that mini-conceptual schema to write up your literature review based on the excerpts that you have in front of you. Don’t forget to include the citations as you write, so as not to lose track of who said what. Repeat this for each section of your literature review.

Once you complete these six steps, you will have a complete draft of your literature review. The great thing about this process is that it breaks down into manageable steps something that seems enormous: writing a literature review.

I think that Foss and Walter’s system for writing the literature review really can work for a dissertation, because a Ph.D. candidate has already read widely in his or her field through graduate seminars and comprehensive exams.

It may be more challenging for M.A. students, unless you are already familiar with the literature. It is always hard to figure out how much you need to read for deep meaning, and how much you just need to know what others have said. That balance will depend on how much you already know.

For faculty writing literature reviews for articles or books, this system also could work, especially when you are writing in a field with which you are already familiar. The mere fact of having a system can make the literature review seem much less daunting, so I recommend this system for anyone who feels overwhelmed by the prospect of writing a literature review.
