Abstract

Search index usage in a large university online catalog system over a six-year period (representing about 15,3 million searches) was investigated using transaction monitor data. Mathematical models of trends and patterns in the data were developed and tested using regression techniques. The results of the analyses show a consistent decline in the frequency of subject index use by online catalog users, with a corresponding increase in the frequency of title keyword searching. Significant annual patterns in index usage were also identified. Analysis of the transaction data, and related previous studies of online catalog users, suggest a number of factors contributing to the decline in subject search frequency. Chief among these factors are user difficulties in formulating subject queries with LCSH, leading to search failure, and the problem of "information overload" as database size increases. This article presents the models and results of the transaction log analysis, discusses the underlying problems with subject searching contributing to the observed decline, and reviews some proposed improvements to online catalog systems to aid in overcoming these problems

Abstract

The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
