Title

¬The future of AACR2

Abstract

Examination of selected rules of the Anglo-American Cataloging Rules, Second Edition, 1988 revision, (AACR2) shows that the rules are oriented towards a paper-based catalog and are, at least to some extent, not suitable for a computer environment. Thorough examination of the objectives and principles of all aspects of cataloging in the computer age is suggested, followed by subsequent development of a new type of "enhanced" code which takes advantage of considerable work done by many ALA and other units in the area of computer-aided retrieval. This code should deal with traditional catalog code questions as well a subject retrieval, catalog design, and computer capabilities. Specific suggestions are made for each section of the proposed code.
