Written specifically for school libraries, the principles given can be applied to any library system which houses books and other media together and has a single, unified list of holdings. Following some general rules for descriptive cataloging, the cataloging principles are given for such non-book materials as: (1) filmstrips, (2) slides, (3) transparencies, (4) microforms, (5) pictures, (6) charts, (7) motion pictures, (8) phonodiscs, (9) phonotapes, (10) models and (11) games. A knowledge of book cataloging and basic cataloging is presupposed. It is emphasized that the subject analysis systems chosen by a particular library for its print collection should be used for all media. As there is no consensus among librarians and audiovisual specialists regarding the proper terms to be applied to many media, a glossary of media designations is included in an attempt to standardize terminology.
