Managing Catalog Data to Enhance Library OPAC Use

Abstract

This presentation illustrates two local projects that have greatly enhanced OPAC use: (1) handling duplicate and obsolete authority records; (2) creatively making use of local subject data. The multi-step processes involved record identification and global deletion of outdated authority records using Voyager catjob program and some easy-to-use external programs. The second project involved data switching from the MARC tag 690 to 650. The change allows the data element to be phrase-searchable and hyperlinkable on OPAC.
