Regional Numerical Union Catalog on Computer Output Microfiche
Get PDFA union catalog of 1,100,000 books on computer output microfiche (COM) in twenty-one Louisiana libraries is described. The catalog, called LNR for Louisiana Numerical Register, consists not of bibliographic information, but primarily of the LC card number and letter codes for the libraries holding the book. The computer programs, the data bank, and output are described. The programs provide the capability for listing over two million entries. Also described are the statistical tabulations which are a by-product of the system and which provide a rich source for analysis
An Interactive Computer-Based Circulation System: Design and Development
Get PDFAn 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
The Shared Cataloging System of the Ohio College Library Center
Get PDFDevelopment 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
Content Designators for Machine-Readable Records: A Working Paper
Get PDFUnder the auspices of the International Federation of Library Association's Committees on Cataloging and Mechanization,. an International Working Group on Content Designators was formed to attempt to resolve the differences in the content designators assigned by national agencies to their machine-readable bibliographic records
Analysis of Search Key Retrieval on a Large Bibliographic File
Get PDFTwo search keys (4,5 and 3,3) are aMlyzed using a probability formula on a bibliographic file of 857,725 records. Assuming random requests by record permits the creation of a predictive model which more closely approximates the actual behavior of a search and retrieval system as determined by a usage survey
Two Types of Designs for On-Line Circulation Systems
Get PDFOn-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
Selective Dissemination of MARC: A User Evaluation
Get PDFAfter outlining the terms of reference of an investigation of user reaction to the selective dissemination of MARCrecords, a summary of the types of users is given. Userresponse is analyzed and interpreted in the light of recent developments at the Library of Congress. Implications forthe future of SDI of MARC in a university setting concludethe paper
