What is Grey Literature?
Grey literature consists of studies produced by the government, industry, or other organizations in the form of reports, working papers, data sets, dissertations, fact sheets, policy documents or standards which do not appear in commercial journals. Grey literature is usually not indexed in standard databases and can be difficult to find. Grey literature should be consulted to reduce the risk of publication bias in the results of a systematic review.
