- Abstract
- Audiovisual materials present special difficulties for cataloguers by virtue of the fact that they must display the materials and take the cataloguing information from the title screens which may be inconsistent with data on the labels. The chief source cataloguing concept for audiovisual materials was examined through a comparison of citations from fully catalogued audiovisual records and their corresponding citations from bibliographic sourcebooks. A complete printout was taken of all AVLINE (National Library of Medicine's Audiovisual Online Catalog) records for videocassettes, slides and software. The comparison revealed much similarity with title and other title information, however, series, producer, credits, and dates were more completely described in the fully catalogued records than in the sourcebook citation. There was no evidence to support cataloguing using only eye readable materials. Cataloguing using the chief source of information consistently provides more bibliographic data
