Development and implementation of an off-line catalog card production system and an on-line shared cataloging system are described. In off-line production, average cost per card for 529,893 catalog cards in finished form and alphabetized for filing was 6.57 cents. An account is given of system design and equipment selection for the on-line system. File organization and programs are described, and the on-line cataloging system is discussed. The system is easy to use, efficient, reliable, and cost beneficial.
On-line circulation systems divide into two types. One type contains records only for charged or otherwise absent items. The other contains a file of records for all titles or volumes in the library collection, regardless of their circulation status. This paper traces differences between the two types, examining different kinds of files and terminals, transaction evidence, the quality of bibliographic data, querying, and the possibility of functions outside circulation. Aspects of both operational and potential systems are considered.
