This paper reviews UNESCO activities for the collection of national production data of audiovisual materials and microforms and presents possible approaches to the task. UNESCO has for some years collected data on the production of printed materials, but while recognizing the need for collecting similar statistics on nonprint media, it has not yet done so. If UNESCO were to undertake the task, it would be necessary to enlist the aid of international associations and the national associations of producers of these materials. A first step would be to contract the drafting of a collection instrument (questionnaire) to include definitions and instructions in consultation with persons designated by the principal international associations concerned. Copies of report forms for microforms as specified by the new American National Standard for Compiling Microform Publishing Statistics are attached as appendices. (RAA)
