Prepared as a guide for the use of an instructor, this document contains two principal components: 84 "exhibits," which could be converted into slides or transparencies, and text, which explains and amplifies the exhibits. The text discusses 14 subject areas: (1) Purpose of Vocabulary Control; (2) Major Components of a Controlled Vocabulary; (3) Gathering Terms; (4) Organizing Terms; (5) The Hierarchical Relationship; (6) The Associative Relationship; (7) Characteristics of Descriptors; (8) The Entry Vocabulary; (9) Scope Notes and Identifiers; (10) Thesaurus Format and Display; (11) Growth and Updating; (12) Computer Use; (13) Vocabulary Factors Affecting the Performance of Information Systems; and (14) Natural Language Systems. In several places, the text suggests topics upon which the instructor might elaborate, and it is noted that the guide could be used for a self-study program. A 10-item bibliography is included. (KM)
