    Abstract
    The focus of this study is the search behavior of remote users of the University of California MELVYL Library System, an OPAC. Transaction logs from randomly selected remote user search sessions are analyzed. Descriptive data on the number and type of searches, choice of search mode and database, number of retrievals, number and type of errors, and use of system HELP facilities are presented. The search data have been cross-tabulated with demographic data on the same group of remote users, collected through an online survey conducted by the authors. Effectiveness of system usage is discussed. A case mode is made for the desirability of additional heuristics in the catalog portion of the system
