- Abstract
- Briefly follows the debate concerning: the relationship between traditional library OPACs and the WWW; possible replacement of USMARC format with SGML; and the possible demise of OPACs that do not migrate to the WWW. Discusses the approach taken by the Text encoding Initative (TEI) in their use of a mandatory TEI header in their standard SGML application as the first since CIP to explore attaching bibliographic information to the item itself to assist cataloguing

- Abstract
- The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

- 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
- 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
- The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features

- 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
- 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
- Subject access functionality has yet to reach its full potential in our current library online public access catalog (OPAC) environment. Controlled vocabularies are used, but not fully available to the user. A summary of earlier research identifying user needs in an online catalog environment and suggested solutions will be presented. Examples of current technologies which incorporate controlled vocabularies such as thesauri and classifications to facilitate subject access in online environments will be introduced

- Abstract
- A major initiative at the Sandia National Laboratories Technical Library, New Mexico, is the provision of desktop access to information for Sandia researchers. During 1995, the library created a home page on the WWW with information on how to link to its client server based OPAC. Through multiple access points, researchers can search the catalogue from their desks and a new initiative is the provision of access to Sandia generated documents by converting them to electronic form, placing them on Sandia's 'internal Web' and linking them to the OPAC bibliographic record. Addresses the processes developed in the library and the procedures for cataloguing these electronic reports, including identification of the bibliographic information and MARC tags to be used

- 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
