Designed as a practical aid to staff members, this guide outlines the functional procedures in a modern school media center and offers practical suggestions for facilitating service to students and teachers. Administrative procedures are described in terms of budgeting; the selection and evaluation of materials; and the technical aspects of acquisition, cataloging, circulation, and collection maintenance. Under the heading of services, suggested teaching aids for student library instruction are listed. Staff and community relations and the use of student assistants are also discussed. Media center facilities are described in terms of desirable spaces and equipment rather than with actual floorplans. Throughout the guide, relevant illustrations and directories of resources are provided. (SL)
