According to Booth (2016), "a mapping review aims at categorizing, classifying, characterizing patterns, trends or themes in evidence production or publication" (p. 14). Grant & Booth (2009) add that the point in conducting a mapping review is to "map out" and thematically understand the pre-existing research on a particular topic including assessing any gaps that could be addressed by future research.
Mapping reviews are not to be confused with scoping reviews and differ as the outcome of a mapping review can be to produce primary research or more reviews. Mapping reviews are also known as systematic maps.
When to Use It: Booth (2016) states that "a mapping review is best used where a clear target for a more focused evidence product has not yet been identified" (p. 14). Mapping reviews are especially useful for topics where there is a lot of preexisting literature, for investing if there are gaps in the literature, and are useful to conduct before larger knowledge syntheses such as a systematic review.
