What is Grey Literature?

Simply put, Grey Literature consists of materials that are unpublished or have been published outside of the typical commercial publishing environment.  Grey literature can consist of reports, articles, presentations, theses, conference proceedings, government publications, and much more.

Grey Literature can be diffcult to locate because it is usually only be found outside of the standard commercial research databases.

If you are conducting an in-depth literature review or systematic review on a particular topic it is important to search for grey literature in addition to studies and articles found in PubMed or CINAHL to ensure that you haven't missed anything important or useful.
