Scoping reviews are a "preliminary assessment of potential size and scope of available research literature. Aims to identify nature and extent of research evidence (usually including ongoing research)." Grant and Booth (2009).
Often a scoping review is confused with a mapping review. They are not systematic reviews, but the methodology is closely related.
