Abstract: An on-line computer-based circulation control system has been installed at the Northwestern University library. Features of the system include self-service book charge, remote terminal inquiry and update, and automatic production of notices for call-ins and books available. Fine notices are also prepared daily and overdue notices weekly. Important considerations in the design of the system were to minimize costs of operation and to include technical services functions eventually. The system operates on a relatively small computer in a multiprogrammed mode.
