Ever since vendors began offering MARC records for e-book collections as part of their subscription contracts, libraries have been adding them to their catalogs, typically via batch loads. This seemingly straightforward process has brought new challenges for catalogers in terms of the load itself, sharing records in a consortial environment, quality and completeness of record content, and access problems.

The UIC Library's ongoing communications with vendors has produced better records
