Grey literature is literature produced by government, academics, business and industry in print and electronic formats, but which is not controlled by commercial publishers. Therefore, grey literature can at times be difficult to identify and obtain. It includes theses and dissertations, conference papers and proceedings, research reports, government documents, technical notes and specifications, proposals, data compilations, etc. Often grey literature does not have an international standard book number (ISBN) or an international standard serial number (ISSN).
It is crucial to note where the term “grey literature” derives from. Grey literature comes from the uncertainty of the status of this information. Grey literature is essentially any document that has not gone through peer review for publication. You may be questioning what is the benefit of looking at this type of literature if it is not peer reviewed? The benefit is that grey literature can be published much more quickly since it does not have to be subjected to the lengthy peer-review process. As a result, in cases where there may not be much information on a topic in peer-reviewed research, grey literature may prove a very valuable source of information.
