- Abstract
- COPAC (CURL OPAC) is a union catalogue, based on records supplied by members of the Consortium of University Libraries (CURL), giving access to the online catalogue records of some of the largest academic research libraries in the UK and Ireland. Like all union catalogues, COPAC is supplied with multiple copies of records representing the same document in the contributing library catalogues. To reduce the level of duplication visible to the COPAC user, duplicate detection and record consolidation procedures have been developed. These result in the production of a single record for each document, representing the holdings of several libraries. Discusses the ways in which both the duplicate detection and record consolidation procedures are carried out, and problem areas encountered. Describes the general structure of these procedures, providing a model of the duplicate record handling mechanisms used in COPAC
