Key takeaways
- A literature review argues; it does not just summarise one source after another.
- Organise by theme, not by author or by date.
- Every review should end by pointing to the gap your research fills.
The literature review is where supervisors judge whether you can think critically, and it is also where students most often go wrong. A weak review lists what each author said; a strong review builds an argument out of what the field collectively knows and does not know.
Search systematically
Start with a focused search using clear keywords in databases relevant to your field. Track what you find, note the key papers everyone cites, and follow their references backward and citations forward. Keep a record so you can describe your search if asked.
Read for arguments, not just findings
As you read, capture each paper's central claim, method, and limitation, not only its result. This is what lets you compare studies later and identify where they agree, disagree, or leave questions open.
Organise by theme
The single biggest improvement you can make is to organise around themes rather than authors. Each paragraph should make an analytical point and use several sources to support it, rather than walking through one study at a time.
- 1Group your sources into three to six recurring themes or debates.
- 2Write a topic sentence for each theme that states your own observation.
- 3Bring in multiple authors to support, complicate, or contrast that observation.
- 4End each theme by noting what remains unresolved.
Be critical, not negative
Critical thinking means evaluating the strength of evidence, not dismissing work. Note methodological limitations, sample sizes, or conflicting results, and explain what they mean for your understanding of the topic.
Land on the gap
A literature review should build naturally toward the gap your research addresses. By the final paragraphs, the reader should feel that your study is the obvious next step.
