Society's love affair with information has led to a proliferation of media that shows no sign of abating. Not surprisingly, such materials constitute an increasingly vital part of any library's collection, and a particular and ongoing challenge to its catalogers.For over two decades, Cataloging of Audiovisual Materials and Other Special Materials has served as the place to go for catalogers of nonprint materials around the world. Individual chapters deal with cartographic materials, sound recordings, videorecordings, graphic materials, three-dimensional artifacts and realia, and kits; all of which are substantially updated; while two additional sections, Electronic Resources and Serials, have been completely rewritten.Each chapter begins with a discussion of the general problems a particular media presents, followed by a statement of applicable AACR2 rules and an overview of existing Library of Congress rule interpretations. Facsimiles of source material, with appropriate coding/tagging, subject headings, and call numbers appear throughout.
