    Abstract
    Das Web 2.0 hat auch bei Bibliotheksnutzern zu veränderten Erwartungshaltungen an bibliothekarische Online-Angebote wie die Kataloge geführt. Diese waren lange Zeit statische Nachweisinstrumente, die heutzutage über das Angebot reiner Bestandsverzeichnisse hinausgehend verschiedene Web 2.0-Funktionalitäten sowie Zusatzinformationen mittels Kataloganreicherung integrierten sollten, um den Erwartungen der Nutzer zu genügen. Die Ergebnisse einer Online-Umfrage unter Nutzern einer Großstadtbibliothek unterstreichen dies: die Nutzer wünschen sich vielfältige Browsingmöglichkeiten, Google-ähnliche Suchmöglichkeiten, zusätzliche Inhalte und ein personalisier-bares Angebot. Welche Funktionen und Inhalte sollte ein Bibliothekskatalog im Zeitalter des Web 2.0 bieten? Am Beispiel der Stadtbücherei Frankfurt wird dargestellt wie Prinzipien des Web 2.0 - u.a. Nutzerfreundlichkeit und Kollaboration - auf das Online-Angebot übertragbar sind, ohne dabei den Personalaufwand, die rechtliche Absicherung der Bibliothek und Fragen der technischen Implementierung zu vergessen.

    Abstract
    Diese Arbeit besteht im Wesentlichen aus zwei Teilen: Der erste Teil beinhaltet eine Einführung in den Begriff Web 2.0 und in die allgemeinen Rahmenbedingungen der zugehörigen technischen Entwicklungen. Des Weiteren werden exemplarische Techniken vorgestellt, die Web 2.0 zugeschrieben werden können sowie einige beispielhafte Anwendungen. Im zweiten Teil wird die Diskussion um Bibliothek 2.0 aufgegriffen, um anschließend näher auf Web 2.0 Techniken in Bibliothekskatalogen bzw. den OPAC 2.0 einzugehen. Verschiedene Techniken, die im OPAC 2.0 Anwendung finden können, werden diskutiert und zuletzt werden einige beispielhafte OPACs vorgestellt.

    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
    Will there be a library catalogue in the future and, if so, what will it look like? In the last 25 years, the library catalogue has undergone an evolution, from card catalogues to OPACs, discovery systems and even linked data applications making library bibliographic data accessible on the web. At the same time, users expectations of what catalogues will be able to offer in the way of discovery have never been higher. This groundbreaking edited collection brings together some of the foremost international cataloguing practitioners and thought leaders, including Lorcan Dempsey, Emmanuelle Bermès, Marshall Breeding and Karen Calhoun, to provide an overview of the current state of the art of the library catalogue and look ahead to see what the library catalogue might become. Practical projects and cutting edge concepts are showcased in discussions of linked data and the Semantic Web, user expectations and needs, bibliographic control, the FRBRization of the catalogue, innovations in search and retrieval, next-generation discovery products and mobile catalogues.

    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
    Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

    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

    Abstract
    The development of networked access to academic library catalogue records has been conspicuously slow compared with that of campus wide information systems in general. In cooperation with its systems suppliers BLCMO, the Pilkington Library, Loughborough, UK, is seeking to remedy this situation by developing an interface that allows users to access its OPAC via the W3. The benefits of such a facility are reflected in BLCMP's decision to incorporate a revised version in the forthcoming release of the commercial Talis system; but problems relating to the 'statelessness' of hypertext tranfer protocol (HTTP) and to the inadequacy of traditional catalogue records as access points for electronic information resources are still causes for consideration

    Abstract
    In this article are compared traditional OPAC systems, enriched OPAC, social OPAC and social cataloguing systems.the aim is to underline new theoretical trends and to offer a taxonomic outline of such tools, according to the interaction level granted to users and to the chance to manage user's generated contents in the point of view of the application of web 2.0 tendecies to libraries, in the library 2.0. At the end, a brief review of softwares, both open source and not, that seem promising for this future application.

    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
    This paper describes a Research Project, funded by the British Library Research and Innovation Centre, from September 1996 to January 1998.1 The Project developed and extensively tested and evaluated a World Wide Web front end called BOPAC2 that allows access to a number of library catalogues via Z39.50 either simultaneously or individually. BOPAC2 is designed to make access to large and complex retrievals simpler. Similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. The design, development and evaluation of the system are described along with suggestions for future work
