The literature review is the chapter most likely to be sent back for rewriting, and almost always for the same reason. It reads as a catalogue: this author found this, that author found that, a third author disagreed. Everything in it may be accurate and it can still be worth a low mark, because a catalogue is not an argument.
What the chapter is actually for
A literature review exists to establish that there is a gap and that your study fills it. Every source you include should be doing one of a small number of jobs: establishing what is settled, showing where the field disagrees, revealing what has not been examined, or justifying the method you intend to use. A source doing none of those does not belong in the chapter.
Organise by theme, not by source
The structural fix is to organise around ideas rather than around papers. Each section addresses a theme or a point of contention, and within it you bring together the several authors who speak to it, showing where they agree, where they conflict, and what the conflict turns on. A single paragraph should routinely cite three or four sources.
- Group sources by the question they answer rather than by publication date
- Foreground disagreement, because that is where the interesting work is
- Say what the disagreement turns on: method, sample, definition or theory
- Note methodological patterns, since they justify your own choices later
- End each theme by stating what remains unresolved
The gap has to be real
Supervisors are practised at spotting a manufactured gap. No one has studied this in my city is rarely a gap worth a dissertation unless there is a reason the location matters. A real gap is a question the existing literature raises but does not answer, a conflict the evidence has not settled, or a population or condition to which existing findings may not transfer, with a reason why.
Once the gap is stated, the transition to your research question should feel inevitable rather than announced. If you have to assert the connection, the review has not yet done its job.
Searching properly
A thin review is usually a search problem rather than a writing problem. Use your library databases rather than a general search engine, record your search terms so the process is reproducible, and follow citation trails both backward from reference lists and forward through citing articles. Set an inclusion boundary early and write it down, because a review with no stated scope invites the question of what you left out.
