What is Grey Literature?

Grey literature refers to any literature that is not a book or content within a journal or magazine and not published by commercial publishers. Usually these sources are not indexed or cataloged, and may be part of the "Deep Web" meaning they cannot be found easily with a web browser. These publications might be conference proceedings, government documents, internally published studies, and other similar forms of documents created by government, academic, organizational and business entities.

Assessing Grey Literature is as important as evaluating any other source from published literature or from the Web. Use these tools to help you determine the credibility of sources:


  • Currency
  • Reliability
  • Authority
  • Accuracy
  • Purpose/Point of View
