- Abstract
- Expanded hours of access and the reduction of peak system loads are often cited as advantages of remote access to OPACs. This argument is based on the assumption that remote users search OPACs when libraries are closed or when there is low internal use. The study tested this assumption by performing a transactional log analysis of the remote and internal use of the OPAC at the Research Libraries of the New York Public Library. Analysis showed that pateerns of remote and internal use differed greatly. A large part of the remote searching occured when the Research Libraries were closed. Compared to internal searching, remote searching was distributed more evenly over the course of the day and the week. Results show that remote access expands the hours of use of the Online catalogue and has potential to reduce peak system loads at the Research Libraries

- 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

- Abstract
- This report presents the results of a survey of users who access the University of California's online union catalog, the MELVYL library system, via microcomputers with modems or connections carried through local or wide area networks. The report includes descriptive statistics on user location, status, subject interest, affiliation, in-library versus out-of-library usage patterns, need for assistance, and desire for new features

- Abstract
- This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users
