Content Access Management (CAM)

Authority Maintenance

Authority control is the process of selecting one form of name or title from among available choices and recording it, the alternatives, and the data sources used in the process. It is essential for effective retrieval of resources. It provides consistency in the form of access points used to identify persons, corporate bodies, and works. Authority control is central to the organization for information.

The Authority Control Team is responsible for authority maintenance work for the University of Illinois online catalog.
