TO FACILITATE EASY REFERENCE, THE ORIGINAL BIBLIOGRAPHY CONTAINS ONLY THREE SECTIONS - SUBJECT, SOURCE, AND AUDIO-VISUAL MATERIALS. THIS SUPPLEMENT, HOWEVER, ADDS A FOURTH SECTION - DISTRIBUTORS FOR AUDIO-VISUAL MATERIALS. THE 'SUBJECT SECTION' LISTS 102 PAGES OF BOOKS, MANUALS, AND PERIODICALS ON 89 SUBJECTS RANGING FROM APPEALS TO WITNESSES. SOURCE CITATIONS FOR DIRECT ORDERING FROM PUBLISHERS ARE LISTED ALPHABETICALLY IN THE 'SOURCE SECTION.' THE 'AUDIO-VISUAL SECTION,' INCLUDED IN RECOGNITION OF THE INCREASING RELIANCE UPON AUDIO-VISUAL MATERIALS IN PROSECUTORIAL TRAINING AND RESEARCH, LISTS BY SUBJECT SELECTED FILMS, AUDIO CASSETTES, AND VIDEO REEL-TO-REEL AND CASSETTE TAPES AVAILABLE FOR RENTAL OR PURCHASE. A BRIEF DESCRIPTION ACCOMPANIES EACH LISTING. ADDRESSES FOR DIRECT ORDERING OF MATERIALS APPEARS IN THE DISTRIBUTORS FOR AUDIO-VISUAL MATERIALS' SECTION.
