Grey literature is a term used to describe information and research produced outside of traditional publishing and distribution channels. It is either unpublished or has been published in non-commercial form from a variety of sources. Therefore, it is not necessarily findable using standard databases and search tools. Grey literature hasn’t been peer reviewed, but it may still be useful and reliable.
Using grey literature will help you:
access current information about emerging research areas
minimise publication bias in systematic reviews
discover raw data that is not available in traditional publications.
