- 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
- 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
- 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
- Presents the results of an evaluation of the Spanish Web OPACs. A checklist approach was employed to access the interface and searching options. Evaluates main page, labels, text, instructional information, online help and page layout. The data gathered allow for the ranking of the OPACs, as well as the identification of weaknesses in the catalogues

- Abstract
- A survey of Japanese OPACs available on the Internet was conducted relating to use of keywords for subject access. The findings suggest that present OPACs are not capable of storing subject-oriented information. Currently available keyword access derives from a merely title-based retrieval system. Contents data should be added to bibliographic records as an efficient way of providing subject access, and costings for this process should be estimated. Word standardisation issues must also be addressed

- 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
