    Abstract
    WWW-OPACs bieten Bibliotheksnutzern die Möglichkeit, von zu Hause oder vom Arbeitsplatz aus über Internet in den Beständen zu recherchieren, unter Umständen sogar Bestellungen aufzugeben oder Verlängerungen vorzunehmen. Scheidet ein Zugang übder das Internet aber aus technischen oder finanziellen Gründen aus, bietet sich als Übergangslösung immer noch der Zugriff via Telefon an. - Am Beispiel der StB Chemnitz wird deutlich, daß dieses Konzept keienswegs überholt ist: Denn obwohl man auch in Chemnitz mittelfristig eine WWW-Lösung anstrebt, soll den Nutzern aufgrund der großen Akzeptanz auch zukünftig der OPAC-Zugriff über Telefon möglich sein. Darüber hinaus wurden in Chemnitz die OPAC-Module von Stadtbibliothek und Universitätsbibliothek gekoppelt, eine Recherche ist an den internen OPAC-Plätzen in beiden Richtungen mit demselben Funktionsumfang möglich

    Abstract
    The primary objective of the present study was to exmine whether readers conducting bibliographic searches in ALEPH - Israel's research library network - tend to search only within the OPAC of the library within which they are working or whether they access the remote OPACs of other libraries. The ALEPH network has a dezentralized database. Therefore, it was possible to examine this question because each library has its own access code and each database can be searched separately. The data were collected by means of a one-page questionnaire lefr beside each terminal in the library of the Graduate School of Library and Archive Studies of the Hebrew University of Jerusalem during an entire academic years. results of analysis of the data collected in this survey are presented in 6 tables

    Abstract
    Provides examples to illustrate the growing use and acceptance of remote access to OPACs. Examines the differences between offering in-house public access and remote access to users and offers suggestions to help address some of the requirements of remote users. Discusses the shortcomings of the bibliographic record, what can be done to enhance the OPAC record, remote access to periodical indexes, access to the physical items represented by the bibliographic records, and the importance of establishing lines of communication with remote users

    Abstract
    Hartford University mounted a DRA Atlas Integrated library system in 1991, using a DECnet/Ethernet network and a VAX 6310 mainframe computer. As VAX VT320 terminals were available in many campus buildings, the library's catalogue could be searched from many locations and could be dialed up by remote users. Commercial databases in MARC format could be mounted on the system and searched with the same commands that users employed for the OPAC. Explains the use of Periodical Abstracts from UMI on the online catalogue. Discusses searching strategies and compares the Periodical Abstracts Ondisc CD-ROM with the tape loaded product

    Abstract
    Computer and communications technology is having a profound impact on libraries and the way in which they serve their users. Discusses online catalogues in libraries, the development of the Internet and OSI, and the development of search and retrieve (SR) protocols to allow standardized access to library catalogues across communications networks. Considers the deployment of SR protocols, problems with interoperability of clients and servers, interlibrary loan possibilities of SR protocols, and the feasibility of electronic document delivery

    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

    Abstract
    Examined two groups of online catalogue users segregated by their method of access to the system: terminals in the library or remote workstations. An online survey collected demographic data, perceptions on source and terminal accessibility, and information on usage, task variety and search satisfaction. Transaction logs furnished data on browsing behavious, while interviews of both groups provided additional information about remote use. Results indicate that remote use is comparable to traditional use

    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
    OPACs in an increasing number of libraries are now available using the Joint Academic Network (JANET). Access has tended to be obstructed, for the casual user, by the lengthy JANET addressing codes and varying log-on procedures required by each library system. Discribed how a communications and menu package on an IBK/PC can be used so that by merely pressing cursor control, return and escape keays, any user can gain access to any one of over 40 OPACs linked to JANET

    Abstract
    Networks allow different users from outside the library to have remote access to library catalogues. These remote users may face problems that differ from the OPAC users' in the library. They may not be comfortable with the computer technology and may not be familiar with the OPAC of the library. Libraries should offer different support services from those provided to on-site users. These users need technical advice as well as special instruction aids and guides to lead them to the information they want to retrieve

    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
