A product of many years experience in a small volunteer church library, this manual is a comprehensive tool for the administration and treatment of audiovisual materials for similar library situations. Administrative concerns--personnel, budget, and procedures--are the focus of the first section. The whole range of general activities, from selection of appropriate materials, through their processing to their promotion, is covered in the document's second and longest section, with samples of record forms used. Then each type of audiovisual aid, e.g., films, slides, maps, and globes (11 groups in all), becomes the subject of its own chapter, where it receives more specific attention based on the pattern of treatment established in the general discussion. Sample catalog cards are used to illustrate different cataloging methods appropriate to each kind of material and bibliographies and sources for the medium conclude each chapter. An index to the whole document is included at the end. (JD)
