A literature review looks like a themed discussion of existing research, grouped by topic or argument rather than listed source by source, showing how studies relate, agree, conflict, and where gaps remain.
UK undergraduate literature reviews typically run 1,500 to 3,000 words as a dissertation chapter, opening with a brief overview of the field before narrowing into themes relevant to the research question.
For example, a nursing dissertation review might group sources under headings like patient safety, staffing levels, and communication barriers. Browse our literature review samples to see real structured examples across subjects.
A strong review synthesises sources rather than summarising them individually, using topic sentences to introduce each theme and critically comparing findings, methods, and limitations across the studies you have selected.
If your literature review needs restructuring or a stronger critical voice, Essays UK’s dissertation writing service provides a model chapter demonstrating correct thematic organisation and referencing for your subject.
