"Scoping reviews have great utility for synthesizing research evidence and are often used to [categorize or group] existing literature in a given field in terms of its nature, features, and volume." Note: Often a scoping review is confused with a mapping review. They are two different types of descriptive reviews and are not systematic reviews, but the methodology is closely related.
According to Grant and Booth (2009), Scoping reviews are "preliminary assessment of potential size and scope of available research literature. Aims to identify nature and extent of research evidence (usually including ongoing research)."
