Systematic Reviews: A How-To Guide

Overview of systematic review steps and resources to assist researchers conducting reviews

What is grey literature?

Grey literature is literature produced by any organisation whose central purpose is not publishing. These organisations include governments, businesses, not-for-profits, health organisations and associations, and more. Searching for grey literature can be difficult because it is not usually indexed within traditional databases. When completing a systematic review, however, it is imperative to find as much evidence as possible, and that means searching beyond academic literature alone.
