Systematic Review vs Literature Review: Which One Are You Actually Writing?

Learn the difference between a systematic review and a literature review, including goals, methods, rigor, and when each review type fits.

A literature review summarizes and interprets scholarship around a topic, often as part of a broader paper or thesis.

If your assignment does not require protocol-level rigor, you are probably writing a literature review, not a systematic review.

No. Most literature reviews are not systematic reviews.
Which one is harder to do?
A systematic review is usually more demanding because it requires protocol design, structured searching, documented screening, and often quality appraisal.
Can a thesis literature review be systematic?
Yes, but only if the project truly follows systematic-review methods rather than simply using the label.
