- Abstract
- Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

- Abstract
- Over the past year, innumerable discussions on the relationship between traditional library OPACs and the newly burgeoning World WideWeb have occured in many libraries and in virtually every library related discussion list. Rumors and speculation abound, some insisting that SGML will replace USMARC "soon," others maintaining that OPACs that haven't migrated to the Web will go the way of the dinosaurs.

- Abstract
- The Venice University Institute of Architecture has developed Easyweb, a software package to integrate its heterogeneous non-compatible bibliographic and multimedia databases, standardise access and create internal links, by transferring all existing OPAC applications to the Web. Features include importation of UNIMARC data, multiple window searching, multibase searching and special applications, e.g. circulation management. Easyweb is notable user friendly and has become the point of reference for OPACs in Italy

- Abstract
- Online catalog users search predominately by subject, yet it is the most difficult search to perform and retrieves records only about one-half of the time. A new generation of OPACs (online public access catalogs) is on the horizon, the Web-based OPAC. Web-based OPACs allow users to access online catalogs through a WWW (World Wide Web) interface and have the potential to improve patrons' ability to search by subject. But will this potential be realized? This article proposes some basic guidelines that can be incorporated into Web-based OPAC interface design to help users perform subject searches more effectively, and evaluates how well Web-based OPACs currently in operation address the subject searching problem

- Abstract
- The World Wide Web (simplified here to "Web") is well-known for its "point and click" graphical user interface (GUI) and hyperlink search and navigate capabilities. When OPACs are placed in this operational context, users can easily hyperlink from a bibliographic display to related search terms, class marks, or bibliographic records. This hyperlinking capability is not available in most conventional text-based OPACs. As more and more users undertake their searches on Web-based information retrieval systems such as OPACs, it is natural to ask, "Are Web-based OPACs more effective retrieval systems than their conventional predecessors?" This paper presents the findings of an experimental study which compared users' search performance, assessments of ease of use, and satisfaction with search results after use of a Web OPAC or its conventional counterpart. The primary questions addressed by this research center on the influence of two experimental factors, OPAC search interface style and search task level of difficulty, on the dependent variables: actual search performance, perceptions of ease of use, and user assessments of satisfaction with search results. It was hypothesized that Web OPACs would be assessed as easier to use and that they would outperform conventional OPACs when measured by actual search results and users' levels of satisfaction with search results. Web OPAC searchers outperformed Text OPAC searchers, but search task level of difficulty is a major determinant of search success. The study also found little association between searchers' level of satisfaction with results and actual search performance

- Abstract
- To access a remote catalogue the searcher can use the Z39.50 standard as interface, which requires appropriate software; or for databases accessible on the WWW use a common gateway interface. The multibase access advantage of Z39.50 can also be obtained through a Web navigator by inserting a Web server/Z39.50 client software connector: this can be located either on the search site, in an intermediary position or on the database site, so determining the range of databases which can be searched. Z39.50 also offers interesting possibilities for joint and local cataloguing: multibase searching can equally be realised on intranets

- Abstract
- Reports results of an evaluation study of 3 WWW based prototypes for bibliographic displays developed as part of an ongoing research project at the Faculty of Information Studies, Toronto University. The development of these prototypes builds upon results obtained in earlier phases of the project that addressed issues of both the content and form of bibliographic displays in OPACs. Anticipation of continued growth in the number of catalogues available through the WWW, combined with research evidence that existing Web based displays have not shown improvement over their text based counterparts, motivated the development of these prototypes for use on the Web. Reports findings from a focus group evaluation of the 3 prototypes and makes suggestions for future research

- Abstract
- This article reports on a model and patterns of use of a library catalog that can be accessed through the Internet. Three categories of users are identified. individuals who perform a search of the catalog, tourists who look only at opening pages of the library catalog's site, and Web spiders that come to the site to obtain pages for indexing the Web. A number of types of use activities are also identified, and can be grouped with the presearch phase (which takes place before any searching begins): the search phase, the display phase (in which users display the results of their search), and phases in which users make errors, ask the system for help or assistance, and take other actions. An empirical investigation of patterns of use of a university Web-based library catalog was conducted for 479 days. During that period, the characteristics of about 2.5 million sessions were recorded and analyzed, and usage trends were identified. Of the total, 62% of the sessions were for users who performed a search, 27% were from spiders, and 11% were for tourists. During the study period, the average search session lasted about 5 minutes when the study began and had increased to about 10 minutes 16 months later. An average search consisted of about 1.5 presearch actions lasting about 25 seconds, about 5.3 display actions, and 2.5 searches per session. The latter two categories are in the range of 35-37 seconds per session each. There were major differences in usage (number of searches, search time, number of display actions, and display time), depending upon the database accessed

- Abstract
- Recherche in Bibliothekskatalogen war, zumindest in deutschen Bibliotheken, bis zur Mitte des 20. Jahrhunderts in der Regel Sache des Personals, eine wirklich erfolgreiche Recherche meist Spezialisten vorbehalten. Nur diese waren in der Lage, häufig unter Einbeziehung diverser Hilfsmittel, Titelwünsche der Leser nach den jeweiligen Katalog- und Bibliotheksregeln in entsprechende Kataloganfragen umzusetzen. Als dann den Bibliothekskunden selbst nach und nach der Zugang zu diesen Zettelkatalogen in den Bibliotheken eröffnet wurde, war für eine erfolgreiche Suche meist "guter Rat teuer". Hilfestellung und "guter Rat", oft schon bei einer simplen Titelsuche wie "Schuld und Sühne" nötig, konnte vom uneingeweihten Leser direkt vor Ort in der Bibliothek eingeholt werden. Elektronische Formen der Kataloge in Bibliotheken, kurz "OPACs" genannt, eröffneten neue, den alten Zettel- und Mikrofichekatalogen völlig unbekannte Suchmöglichkeiten. Sie zogen aber auch neue Fragestellungen nach sich, besonders zum Handling und zur Suchstrategie. Zumindest dem "fragemutigen" Nutzer konnte und kann dabei vor Ort in den Bibliotheken immer noch direkt geholfen werden. Diese Hilfestellung entfällt jedoch bei allen Bibliotheks- und Verbundkatalogen, die im Internet als so genannte "Web-OPACs" angeboten werden. Sie erreichen einen viel größeren, dafür aber anonym bleibenden Interessentenkreis, vom absoluten Bibliothekslaien bis zum kundigen Bibliotheksnutzer. Diese aktiven und potentiellen Nutzer treten mit den unterschiedlichsten Anforderungen und Fragestellungen an solche Web-OPACs heran. Ein Web-OPAC muss demnach so gestaltet sein, dass er für Laien und Profis gleichermaßen nutzbar ist und dabei möglichst wenige Fragen überhaupt erst aufkommen lässt, im Idealfall also über eine selbsterklärende Oberfläche verfügt. Hilfetexte müssen die nicht vorhandene persönliche Hilfestellung kompensieren helfen. Sie sind also übersichtlich, verständlich und zielgerichtet einsetzbar zu gestalten.
