grey literature

Grey literature refers to research, reports, or information produced by organizations that are not published through traditional commercial publishing channels. Examples include government reports, policy papers, technical documents, theses, and conference proceedings. These materials often contain valuable, timely, and specialized information that may not be easily found in standard academic journals or books. While they can be harder to locate, grey literature is an important resource for comprehensive research, providing insights from industry, government agencies, and organizations that may not be widely disseminated through conventional publishing outlets.
