This five-year plan of the Chicago Public Library revises the plan of 1976-1980. Several operational/procedural objectives have been dropped and incorporated in normal operations. New goals, objectives, and tasks are service-directed with special attention to expanding services to affiliated and other cooperating Chicago libraries. The specific goals of the system are to provide: (l) system-wide services and study through interlibrary loan, interagency and communication networks, and cooperating programs, to member and affiliate libraries for their clientele, individuals and institutions in Chicago and beyond; (2) the services of a central reference and resource center to Chicago citizens and others through interlibrary loan and ILLINET; (3) the best possible service to Chicago communities through a system of branch and regional libraries, and reading and study centers; and (4) the services of a collection of popular reading materials, children's materials, and cultural and educational programming for Chicagoans through a cultural center.
