What is grey literature? Grey (or gray) literature is literature that is not published in traditional academic or commercial publishing venues. Grey lit includes resources like clinical trials, registries, government publications, policy papers, white papers, working papers, theses and dissertations and much more.
Why grey literature? Evidence-based practice is targeted at looking at the "bigger picture" of evidence out there to inform clinical decision-making. Sometimes the publishing bias of "traditional" literature can mean we do not always have other types of evidence easily accessible.
A word of caution. While grey literature has an important part in research and reducing bias, grey literature does not adhere to the same peer-review process, therefore, it is important to use critical evaluation and appraisal when searching and reviewing it.
