    Abstract
    Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects and the conceptual aspects of system use is reviewed, with the conclusion that more similiratiy exists across types of systems in conceptual than in mechanical problems. Also discussed are potential sources of the problems, due either to individual characteristics or to system variables. A series of research questions is proposed and a number of potential interim solutions ae suggested for alleviating some of the problems encountered by users of information systems

    Abstract
    A survey was conducted during 1987 to identify how online catalog users interact with various aspects of the catalog's authority control structure. Questionnaires were sent to major online catalog system vendors and to selected university libraries and networks known to have developed in-house online catalogs; additional copies were distributed to ACIG meeting participants during the ALA conference in San Francisco, June 1987. Twenty-one usable responses were received, twelve describing commercially available systems and nine from lacally developed systems.

    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.
