    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
    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
    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
    Die verschiedenen unter dem Schlagwort "Bibliothek 2.0" zusammengefassten neuen Dienste und Komponenten wie etwa Wikis, Tagging-Systeme und Blogs sind seit einiger Zeit in aller Munde und dringen über Fortbildungsveranstaltungen, Konferenzen und Publikationsorgane immer mehr in das deutschsprachige Bibliothekswesen ein. Darüber hinaus gibt es öffentlich geförderte Projekte zu bibliothekarischen 2.0-Themen und sogar ein Projekt, welches sich explizit einen 2.0-Katalog zum Ziel gesetzt hat. In diesem Beitrag soll es nun nicht um die Vorstellung eines weiteren Projekts im Dienste des Themas "Bibliothek 2.0" gehen, ebenso hat dieser Beitrag nicht den Anspruch, die Diskussion über die möglichen Vor- oder Nachteile dieser Thematik auf theoretischer Ebene voranzubringen. Vielmehr wird hier ganz praktisch aus Sicht einer kleinen Universitätsbibliothek, der Bibliothek der Helmut-SchmidtUniversität (HSU) - Universität der Bundeswehr Hamburg, aufgezeigt, wie das Thema "Web/Bibliothek 2.0" durchaus neben und in Unterstützung von weiteren nutzerorientierten Servicedienstleistungen auch in kleinen Schritten positive Auswirkungen für die Nutzerinnen und Nutzer haben kann. Der Focus wird dabei auf dem zentralen Arbeits- und Rechercheinstrument der Bibliotheksnutzer liegen, dem Bibliothekskatalog. Speziell wird es darum gehen, wie auf relativ einfache Art und Weise durch Anwendung verschiedener Elemente anderer Dienste und Anbieter sowie das Aufgreifen von Schnittstellen und wenig aufwendigen Verbesserungen, Mehrwert für die Nutzerinnen und Nutzer zu erzielen ist. Ein zentraler Begriff bei fast allen Überlegungen, die im Zusammenhang mit der Verbesserung und Anreicherung des Kataloges stehen, war und ist das Thema "Mash-up". Unter Mashups - ein Begriff, der gerade im Zusammenhang mit dem Thema "Web 2.0" im deutschsprachigen Raum eingeführt und adaptiert wurde - wird das Verfahren bezeichnet, Web-Inhalte neu zu kombinieren. Dabei nutzt man bei und für Mashups offene "APIs" (Application Programming Interfaces, also offene Programmierschnittstellen), die von anderen Web-Anwendungen zur Verfügung gestellt werden.

    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

    "Most Web search engines accept natural language queries, perform some kind of fuzzy matching and produce ranked output, displaying first the documents that are most likely to be relevant. On the other hand, most library online public access catalogs (OPACs) an the Web are still Boolean retrieval systems that perform exact matching, and require users to express their search requests precisely in a Boolean search language and to refine their search statements to improve the search results. It is well-documented that users have difficulty searching Boolean OPACs effectively (e.g. Borgman, 1996; Ensor, 1992; Wallace, 1993). One approach to making OPACs easier to use is to develop a natural language search interface that acts as a middleware between the user's Web browser and the OPAC system. The search interface can accept a natural language query from the user and reformulate it as a series of Boolean search statements that are then submitted to the OPAC. The records retrieved by the OPAC are ranked by the search interface before forwarding them to the user's Web browser. The user, then, does not need to interact directly with the Boolean OPAC but with the natural language search interface or search intermediary. The search interface interacts with the OPAC system an the user's behalf. The advantage of this approach is that no modification to the OPAC or library system is required. Furthermore, the search interface can access multiple OPACs, acting as a meta search engine, and integrate search results from various OPACs before sending them to the user. The search interface needs to incorporate a method for converting the user's natural language query into a series of Boolean search statements, and for ranking the OPAC records retrieved. The purpose of this study was to develop a relevancyranking algorithm for a search interface to Boolean OPAC systems. This is part of an on-going effort to develop a knowledge-based search interface to OPACs called the E-Referencer (Khoo et al., 1998, 1999; Poo et al., 2000). E-Referencer v. 2 that has been implemented applies a repertoire of initial search strategies and reformulation strategies to retrieve records from OPACs using the Z39.50 protocol, and also assists users in mapping query keywords to the Library of Congress subject headings."

    Abstract
    It's clear that today's typical library users are Web-sawy and have very high expectations. Librarians need to offer interfaces on Web sites that match or exceed those found on the commercial Web. Paired with high-quality content that's selected and created by librarians, a state-of-the-art Web interface is a compelling destination for users.

    Abstract
    Purpose - This exploratory study sets out to describe the ways in which end-users exchanged information between the web and a web online catalog, how they searched one device based on what they knew about the other, and their experiences in navigating between the two devices. Design/methodology/approach - Thirty-one participants were observed searching the web or a web online catalog. After the observations, an interview guide was used to ask targeted questions. Findings - The findings suggest that people familiar with the use of traditional online catalogs were more comfortable using web tools than those who lacked online catalog experience. People who had recent web experience expected online catalog searching to be similar to web searching. However, drawing too close an association between the two systems sometimes caused difficulties when the searching protocols varied, like keyword searching versus selecting an index. Research limitations/implications - Some limitations of the study include a small sampling size, varied responses to interview questions, obtrusive procedures, and lack of generalizability to groups or settings dissimilar from the one in this study. Originality/value - This study provides a rare look into the challenges faced by a diverse group of public library users on the web. It is instructive for practicing librarians and researchers.

    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
