The University of Limerick Library outsourced the cataloguing cleanup of over 300,000 records to improve consistency and prepare for uploading records to OCLC. The cleanup standardized formatting, applied authority control and Resource Description and Access enrichment according to the supplier Backstage's program. It took 3 months to load back the cleaned records 5,000 at a time and addressed challenges like location name changes. The benefits included records ready for OCLC, consistent formatting, and improved discovery capabilities.
