COPAC: The new national OPAC service based on the CURL database

COPAC is the new OPAC providing a unified interface to the consolidated database of the Consortium of University Research Libraries (CURL). This paper provides a brief overview of the background to CURL and the COPAC project, describing the main content of the COPAC database. Having multiple contributors to the database inevitably results in some record duplication. Deduplication and record consolidation are being carried out in the production of the COPAC database and the general procedures involved are described. COPAC is accessible via a Text interface and a Web interface. Each interface is discussed using example screens to illustrate the search process. Now that the initial COPAC service is in operation, further developments are taking place across several fronts and these are described briefly.
