  Abstract: The purpose of authority control is to ensure consistency in representing a value - a name of a person, a place name, or a term or code representing a subject - in the elements used as access points in information retrieval. The primary purpose of this study is to produce a framework that will provide a clearly stated and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs.

  Abstract: The primary purpose of this study is to produce a framework that will provide a clearly and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs. The role of the FRSAR Working Group was defined in the following terms of reference: - To build a conceptual model of Group 3 entities within the FRBR framework as they relate to the aboutness of works; - To provide a clearly defined, structured frame of reference for relating the data that are recorded in subject authority records to the needs of the users of that data; - To assist in an assessment of the potential for international sharing and use of subject authority data both within the library sector and beyond.

  Abstract: Subject access to information has been the predominant approach of users to satisfy their information needs. Research demonstrates that the integration of controlled vocabulary information with an information retrieval system helps users perform more effective subject searches. This integration becomes possible when subject authority data (information about subjects from authority files) are linked to bibliographic files and are made available to users. The purpose of authority control is to ensure consistency in representing a value-a name of a person, a place name, or a subject term-in the elements used as access points in information retrieval. For example, "World War, 1939-1945" has been established as an authorized subject heading in the Library of Congress Subject Headings (LCSH). When using LCSH, in cataloging or indexing, all publications about World War II are assigned the established heading regardless of whether a publication refers to the war as the "European War, 1939-1945", "Second World War", "World War 2", "World War II", "WWII", "World War Two", or "2nd World War." The synonymous expressions are referred to by the authorized heading. This ensures that all publications about World War II can be retrieved by and displayed under the same subject heading, either in an individual institution's own catalog or database or in a union catalog that contains bibliographic records from a number of individual libraries or databases. In almost all large bibliographic databases, authority control is achieved manually or semi-automatically by means of an authority file. The file contains records of headings or access points - names, titles, or subjects - that have been authorized for use in bibliographic records. In addition to ensuring consistency in subject representation, a subject authority record also records and maintains semantic relationships among subject terms and/or their labels. Records in a subject authority file are connected through semantic relationships, which may be expressed statically in subject authority records or generated dynamically according to the specific needs (e.g., presenting the broader and narrower terms) of printed or online display of thesauri, subject headings lists, classification schemes, and other knowledge organization systems.
