Re-engineering the OPAC using transaction logs
Source
Libri. 47(1997) no.2, S.67-76
Year
1997
Abstract
Describes an attempt, by Illinois University at Chicago (IUC) Library to respond to user needs as they are revealed in transaction logs of OPAC use. Illustrates success in improving access to catalogue records through a reengineering process. Outlines the IUC Library Reengineering Project, the administrative structure to study transaction logs, and the resultant managerial decisions. Notes the changes made to sreen display and to the OPAC. Focusing on customer satisfaction, IUC catalogue librarians joined forces with colleagues to identify Usrs' unmet needs and preferences through transaction log analysis. In order to minimize mismatches between users' expectations and services actually provided, IUC catalogue librarians studied logs and adjusted the OPAC. Descrinbes the specific efforts to increase access to the library's collections and the steps taken to enhance and customize bibliographic and authority records. Concludes that transition log analysis has enabled IUC to alter the form and content of its OPAC to fit the changing needs of diverse and widely disoersed users
