This manual provides practical information on the planning, organization, and operation of school libraries. Some of the guidelines differentiate between small libraries with minimal collections and larger, better-equipped libraries with more resources. Introductory materials include definitions of terms used in this manual. Guidelines are then presented for eight areas of library operations: (1) library policy; (2) how to organize the collection, including cataloging; (3) rules for filing cards in the library catalog; (4) repairing books; (5) circulation procedures, including a brief mention of automated circulation systems; (6) services to teachers, administrators, and students, including the teaching of library skills and suggested library programs; (7) furniture and equipment; and (8) a description of a model school library, including space allocation, furnishings, and the collection. An alphabetical table of Dewey Decimal Classification numbers for various categories of library materials and a list of Dewey Decimal Classification numbers adapted for schools are appended. A 13-item bibliography--of which 11 items are in English--and a subject index are also provided. A list of IFLA professional reports in English together with an order form is included. (BBM)
