In 2016, Cataloging modified 91,560 bibliographic records in the SWAN cluster database. It is important to keep up with these corrections, both to improve intellectual access, and to be ready down the road if we migrate to another ILS, or if BibFrame is implemented. In 2016, Cataloging modified 11,175 item records (ours) in the SWAN cluster database. This was not NEW cataloging, but making some change to the status or call number of an item added earlier. Database cleanup is unseen by the public, but it is important to correct any errors in subject or name headings on bibliographic records so that patrons will discover all of the resources we have by or about a person or a subject.
