| contents | A State-Wide Union Catalog Feasibility Study. Final Report on Project III--FY 1976. Williams, Martha E. MacLaury, Keith D. Cataloging College Libraries Computer Storage Devices Feasibility Studies Information Storage Library Automation Library Research Library Technical Processes Union Catalogs The objective of the project was to develop an inexpensive and effective technique for matching records in multiple fields in order to build a union catalog containing only one representation of a given book. The Information Retrieval Research Lab (IRRL) developed a prototype system called IUCS (IRRL Union Catalog System) by testing various techniques for matching records against large test files of machine-readable records from major institutions that maintain their catalogs in machine-readable form. IUCS involves four major steps: (1) a pre-processing step which converts incoming files into IUCS form; (2) a first pass screen which matches records according to an efficient title-date matching key; (3) a second pass screen which provides more refined matching of the potential duplicates located in the first pass; and (4) a post-processing step which merges the new records into the existing MASTER file to create a union catalog. These procedures were tested by generating a union catalog of three sample files from Ohio College Library Center, Northwestern University, and the University of Chicago. The feasibility study proved it is possible to automatically generate a union catalog with few mismatches or missed matches, and to create and update this catalog economically. (Author/JAB) |
