As a part of the York University's academic planning process, the library staff prepared a list of possible alternatives for 26 library functions to be used as a basis for the development of a three to five year planning guide. Compiled over a period of two months, these represent a range from pie-in-the-sky to bare-boned or eliminated operations. Included are options for audiovisual services, automated systems, cataloging, circulation services, various aspects of collections, equipment and furnishings, hours of service, cooperation and loans, library management, online searching, acquisitions, reprography, physical facilities, public relations, reference services, and the reserve collection. A five-year plan for development of a minicomputer-based library system is appended. (Author/RAA)
