Explain Meaning of grey literature.

Grey literature refers to information, research, or documents that are not commercially published or widely accessible through traditional academic channels. It includes reports, theses, conference papers, government documents, and other non-peer-reviewed materials. Grey literature often provides valuable insights, diverse perspectives, and up-to-date information outside the mainstream scholarly publishing. It is a valuable resource for researchers, policymakers, and practitioners seeking comprehensive and varied sources of information beyond conventional academic journals and books.
