Title
Using transaction log analysis to improve OPAC retrieval results
Source
College and research libraries news. 59(1998) no.1, S.39-50
Year
1998
Abstract
Reports results of the work of the Transaction Logs Task Force, composed of public and technical services librarians charged with reviewing OPAC to identify library wide problems and issues. This OPAC transaction log analysis study compared data derived from 2 sets of logs within a 6 month period. Analysis of the first set of data revealed that users experienced difficulty with basic searching techniques. The OPAC introductory screens were simplified and clarified to help users improve search success rates. The second set of data, analyzed after screen changes had been made, showed statistically significant differences in search results. Concludes that regular monitoring of OPACs through transaction log analysis can lead to improved retrieval when changes are made in response to an analysis of user search patterns
