Educational Media Catalogs on Microfiche (EMCOM) is a collection of catalogs from audiovisual software distributors. These are firms which sell, rent, or distribute on a free-loan basis various films, filmstrips, videotapes, media kits, transparencies, slides, and other visual aids in current circulation among schools, universities, and businesses. The catalogs in this collection are identified by the name of the distributing or marketing agency. The fiche on which the catalog of a particular organization appears can be found by consulting the hard-copy, alphabetical index. The main body of this 1975 edition of EMCOM consists of the alphabetical index by distributor's name and ninety-two 98-frame positive microfiche. The catalogs of both major and minor distributors which were available in print as of March, 1975 are included. Other catalogs which are expected to appear during the rest of the year will be added to this main body in the form of supplementary fiche. (Author/SL)
