These rules provide techniques for cataloging the various types of aural records: discs, cartridges, cassettes, cylinders, etc. They provide only the additions and exceptions that must be made to the rules in Chapters 1, 6, and 13 of the Anglo-American Cataloging Rules, including the provision of all the technical specifications necessary to enable a prospective user to know whether or not the recording can be reproduced on an instrument available to him. The rules are listed in outline form with examples. (Author/PF)
