Gray literature
Gray literature refers to information produced by organizations that is not published through traditional commercial or academic channels. Examples include government reports, technical manuals, conference papers, theses, and policy documents. These materials are often not peer-reviewed or widely distributed through commercial publishers, making them less accessible but still valuable for specialized research and decision-making. Gray literature provides timely, relevant data that can complement published literature, offering insights from organizations and experts that might not be available elsewhere.
