Grey Literature Resources

What is grey literature?

Grey literature is the term used to describe literature that is not formally published as a book or journal article (Higgins, 2011), including:

  • conference proceedings
  • dissertations and theses
  • governmental or private sector research
  • ongoing or unpublished clinical trials

Grey literature resources:

Some library databases contain grey literature in addition to journal articles. For example, PsycINFO includes dissertations; Embase and Medline/PubMed include conference proceedings. Library databases like Medline/Pubmed, however, do not provide comprehensive coverage of grey literature so other resources should be searched to identify literature that is not formally published.


Clinical trials registries:

For quantitative systematic reviews of healthcare interventions, it is strongly recommended to search clinical trial registries for on-going and unpublished trials in order to limit publication bias. Refer to Section 6.2.3 Unpublished and Ongoing Studies in the Cochrane Handbook for Systematic Reviews of Interventions for more information.
