This Society of American Archivists presentation (Chicago, Ill., 2007)explores controlled vocabulary, which is a collection of preferred terms used to categorize content. A controlled vocabulary is considered necessary in order to reconcile all variations on search terms used to express a concept, and to differentiate among all possible meanings of a word.
Subject searching in a digital environment is a major form of access to information; researchers looking for information on the same topic do not necessarily think of the same vocabulary to search for it.
