Folgerpedia – Authority Control

Authority control in a library environment is the establishment and maintenance of consistent forms of names and terms to be used as authorized access points in records of the library catalog. Authorized access points must not only be consistent, each one must be unique. Traditional library practice focused on controlling names (personal, corporate, governmental, and geographic), works, and subjects. While authority control has always been important for library catalogs, with the growth of new environments of linked data it is becoming even more so, with increasing elements in the catalog being represented by authorized forms. (One example: using authorized terms for occupations in authority records.)
