A comprehensive set of rules having the widest practical utility in all types of organizations engaged in the collection and use of nonbook materials is proposed. Since this code is also offered as a draft revision to the Anglo-American Cataloguing Rules (AACR), it is correlated to the AACR and, when appropriate, provides reference to it. The nonbook cataloging rules are divided into four sections: Chapter 1 (General Rules) sets out the general principles, procedures, and requirements common to all the nonbook materials for which these rules are intended. Chapters 2 (Graphics and Three-dimensional Representations), 3 (Motion Pictures), and 4 (Sound Recordings) are supplementary to chapter 1, and each sets out only the special provisions necessary for its range of materials, where these extend or modify the general provisions of chapter 1. An index is provided correlating various types of median and graphics to the special rules covering their treatment in cataloging. (Author/SL)
