    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.
