SWALCAP On‐line Circulation System: Plans and Progress

The central computer, situated at Bristol, is a Rank Xerox Data Systems 530 and this will be linked to mini‐computers and terminals in cooperating libraries by Datel 2400 lines. Initially the computer will be used for the circulation system; cataloguing and book order systems will follow without major alteration to the central configuration. The operation of the circulation system for monographs and periodicals, the file structure and control parameters are described in detail. The 22 supplementary facilities are listed in a table, and figures illustrate the equipment, an example of an author/title enquiry, and the loan parameters.
