Currently being developed by the State Library of Queensland, Australia, ORACLE (On-Line Retrieval of Acquisitions, Cataloguing, and Circulation Details for Library Enquiries) is a computerized library system designed to provide rapid processing of library materials in a multi-user environment. It is based on the Australian MARC format and fully integrates the three sub-systems of acquisitions, cataloging, and circulation. The system has automated authority control, and the authority files are available online for editing and consultation; online searching is possible by name, title, series, subject, ISBN, ISSN, and LCN. Libraries using the system can share records and adjust these to suit local requirements, and consult the union catalog online. Written in COBOL, ORACLE operates on a Control Data CYBER 72-16 computer and is scheduled for completion by June 1980. (Author/JD)
