Levy Library Research Synthesis and Systematic Review Services: Other Review Types

What Are Some Other Review Types?

Word cloud with different types of reviews

There are many, many different types of reviews. The list below is not a comprehensive one, but shows some of the different types of reviews you may encounter in the research literature. If you have a question about one of these, or a review type not listed here, feel free to contact us via our Ask-A-Librarian service!

Rapid Reviews

These are systematic reviews that are done in a short period of type, often less than five weeks; because they are done so quickly, they omit certain sections of a traditional systematic review, making the methodology less rigorous. Rapid reviews should be undertaken only when there is a specific information need on a deadline.

Umbrella Reviews

Also called overviews of reviews. These are systematic reviews of systematic reviews.

Mapping Reviews

Similar to scoping reviews, these reviews are question-based rather than topic-based.

Mixed Methods Reviews

These reviews combine qualitative and quantitative studies to address the same overlapping or complementary review questions.

Realist Reviews

These are systematic reviews that provide explanations for why complex interventions may or may not work.
