The actual conditions in classifying A.V. materials have not been standardized among Japanese schools and universities. It is, however, necessary to devise a unified classification system, not only because A.V. materials have been continually increasing in number and kind, but because the amount of information exchanged among schools is likely to increase in the future. Based on the response to a questionnaire, a standard classification system is presented in this paper. The contents are as follows: 1. Introduction 2. Results of the questionnaire 3. New classification system (1) language of the materials (2) aim and field of the materials (3) form of the materials 4. Items necessary for the input 5. Conclusion It is hoped that this new classification system will be revised and adapted by every school, university and library.
