authority control

Authority control is a method used in libraries and information systems to maintain consistent identification of subjects, creators, or works. It ensures that names, titles, and subjects are standardized, preventing confusion caused by variations or similar names. For instance, many authors may have the same name, and authority control helps distinguish between them, linking their works accurately. This systematic approach improves cataloging, searching, and retrieval of information, making it easier for users to find reliable and precise resources. Ultimately, it enhances the organization and accessibility of knowledge within libraries and databases.
