German: Normdatei

A form of controlled vocabulary that consists of information on entities (e.g. persons, topics, geographic entities, works) which is amalgamated in authority records. Authority files ensure that the holdings of libraries, museums and archives can be catalogued (and consequently retrieved) using standardised name forms; however, they also perform other tasks, e.g. by serving as a knowledge base or linking authority data of different origins.
