Content, Media, and Carrier (336/337/338) Fields in the Public Display.

This study seeks to determine if libraries are displaying the content type, media type, carrier type (336/337/338) fields to the public in their library systems and if they are continuing to use (general material designator) GMDs in their records. It also examines how these new fields are labeled, what types of icons are used, and how specific these icons are. The largest 100 libraries in the United States are examined. [ABSTRACT FROM AUTHOR]
