Intended to provide media staff, library personnel, and educators with a bibliographical guide to commercially-produced educational slides, this computer computer-generated listing contains over 20,000 entries. The volume is divided into three principal sections: (1) a subject guide to educational slides including a subject heading outline and an index to the subject headings, (2) an alphabetical listing of the slides, and (3) a directory of producers and distributors including separate alphabetical listings by code and name. Slides are listed in the alphabetical section individually and under series titles. Each entry includes title and subtitle, size and physical description, number of slides in set, stock or color code, brief description of the contents, audience or grade level, producer and distributor codes, and year of release.
