Over 200,000 distinct items of instructional material are indexed in this seven volume annual directory. They are presented in 600,000 entries under more than 225,000 different topics. Information in the directory is divided into two sections: the instructional materials index and the source index. The instructional materials index is organized alphabetically by the topic of the item and includes information about the audience level, the medium, the price, the source, the title, and the catalog in which the item is described. Materials which might be looked up under several topics are given complete entries under each, eliminating cross-references. The source index provides names, addresses, and telephone numbers for each publisher, producer, or exclusive distributor whose offerings are included in the instructional materials index. Also provided are the full title of each catalog referenced in the instructional materials index and a summary of its contents. Information request cards are bound into each volume to aid in contacting sources for information, catalogs, or samples. The organization of the directory allows the user to create a multi-media package, develop an entire curriculum collection, organize a collection in depth, or assemble a collection for contrast and comparison.
