What makes a good literature review source?
A literature review maps the existing research on your topic — what's known, what's debated, and where the gaps are. The best sources are credible, directly relevant to your research question, and represent both the foundational studies and the most recent developments in the field.
Reviewers look for breadth and balance: a review built on one or two papers looks thin, while one that synthesises a range of peer-reviewed studies shows you understand the wider conversation.
What to look for in each source
- Directly relevant to your research question or scope
- Peer-reviewed and from a credible journal or publisher
- A mix of seminal works and recent studies
- Represents different viewpoints, not just one side
- Methodologically sound, with evidence you can evaluate
- Cited by others working on the same problem
How to build your source list
Define your scope first
Write a clear research question and the boundaries of your review. A focused scope keeps your search manageable and your review coherent.
Work outward from key papers
Find a few central studies, then follow their citations forward and backward to discover the wider body of related work.
Track why each source belongs
Note how each paper relates to your question as you go. That running map becomes the backbone of your written review.
