This classification system was constructed to provide a controlled vocabulary for current educational nonbook materials, especially films and videocassettes. It is designed to help users catalog nonprint materials in any given subject area and at any grade level easily and quickly. The main arrangement is an alphabetical display of terms followed by their cross-references in a word-by-word alphabetizing sequence. An additional display includes the grouping of the terms under broad subject categories to provide an easy access point to the terms in the thesaurus; this arrangement serves as an informal table of contents to the vocabulary. Terms were collected by consulting "Sears Guide to Subject Headings,""Thesaurus of ERIC Descriptors,""The Film File,""Dewey Decimal Classification,""The Core Media Collection for Elementary Schools,""The Core Media Collection for Secondary Schools," and the film catalogs of a number of New York State BOCES (Boards of Cooperative Educational Services). The acceptability of terms to be included was determined by systematic perusal of film, videocassette, and filmstrip annotations of the Delaware-Chenango BOCES holdings. (Author/THC)
