    Abstract
    - ViFas können Social Bookmarking nutzen, um neue Quellen zu erschließen (Personalknappheit). - Der Erfolg ist allerdings davon abhängig, dass eine kritische Masse an Nutzerinnen und Nutzern erreicht wird. Bei den zu erwartenden fachlich spezialisierten Nutzerinnen und Nutzern einer ViFa kann diese sicherlich vergleichsweise niedriger sein. - Delicious erfährt derzeit bereits eine intensive Nutzung, so dass hier deutliche Überschneidungen mit den EconBiz Internetquellen erkennbar sind. Bei Mister Wong ist dies noch zu gering ausgeprägt. - Großes Potential ist vorhanden wenn viele Nutzerinnen und Nutzer viele Inhalte einbringen.

    "Die Europäische Union hat zum ersten Mal eine gemeinsame digitale Bibliothek. Auf dem Internetportal www.europeana.eu stehen seit Donnerstag fast drei Millionen Dokumente, Bücher, Gemälde,Filme und Fotografien aus europäischen Sammlungen zur Verfügung, teilte die EU-Kommission mit. Bereits in den ersten Stunden nach der Freischaltung besuchten mehr als zehn Millionen Internetnutzer die Seite, die vorübergehend zusammenbrach. Die Zahl der Server wurde daraufhin von drei auf sechs verdoppelt. "Wir hätten uns in unseren kühnsten Träumen nicht vorstellen können, dass es einen solchen Ansturm auf Europeana gibt", sagte EU-Medienkommissarin Viviane Reding in Brüssel. Bis 2010 sollen auf dem Portal zehn Millionen Objekte in allen EU-Sprachen abrufbar sein. Mehr als 1000 Archive, Museen und Bibliotheken lieferten bereits digitalisiertes Material. Die Kommission stellt zwei Millionen Euro pro Jahr für den Unterhalt der Plattform bereit. Die Kosten für die Digitalisierung tragen die Mitgliedstaaten. Bisher ist nur ein Prozent aller europäischen Kulturgüter elektronisch verfügbar. Um die angestrebte Zahl von zehn Millionen Werken bis 2010 zu erreichen, müssen die Staaten nach Schätzung der Kommission zusammen weitere 350 Millionen Euro in die Hand nehmen. Wie viel die Mitgliedstaaten bisher aufbrachten, blieb offen. Die EU will die Erforschung und Entwicklung von Technologien in dem Bereich in den kommenden zwei Jahren mit 119 Millionen Euro fördern. Die EU-Kulturminister sprachen sich dafür aus, das kulturelle Angebot im Internet weiter auszubauen und gleichzeitig ihren Kampf gegen Online-Piraterie zu verstärken. "Wir wollen legale glaubwürdige Angebote für Verbraucher schaffen", sagte die französische Ressortchefin Christine Albanel, die derzeit die Ministerrunde führt"

    "Brüssel. Die erste gemeinsame Online-Bibliothek der Europäischen Union ist nach nur wenigen Stunden wegen technischer Probleme wieder abgeschaltet worden. Ein unerwarteter Besucheransturm legte das Portal www.europeana.eu lahm, sagte ein Sprecher der EU-Kommission am Freitag in Brüssel. Die 20 Millionen Klicks pro Stunde habe die Seite nicht verkraftet. "Wir waren ausgerüstet für fünf Millionen Klicks", begründete der Sprecher die Panne. Spätestens bis Mitte Dezember soll die Seite wieder zur Verfügung stehen. Zuvor müsse zusätzliche Computerkapazität im Rechenzentrum der Universität Amsterdam angemietet werden. Bereits am Donnerstagmittag war die Zahl der Server von drei auf sechs verdoppelt worden, nachdem die Seite bereits in den ersten Stunden nach der Freischaltung vorübergehend zusammengebrochen war. "Die Kosten können noch aus dem Budget der Europeana abgedeckt werden", sagte der Sprecher. Europeana macht Dokumente, Bücher, Gemälde, Filme und Fotografien aus europäischen Sammlungen kostenlos im Internet zugänglich. Bisher sind dort knapp drei Millionen Objekte eingestellt, bis 2010 sollen es zehn Millionen sein. Mehr als 1000 Archive, Museen und Bibliotheken haben bereits digitalisiertes Material geliefert. Die Kommission stellt zwei Millionen Euro pro Jahr für den Unterhalt der Plattform bereit. Die Kosten für die Digitalisierung tragen die Mitgliedstaaten."

    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
    With the development of the World Wide Web, the "information search" has grown to be a significant business sector of a global, competitive and commercial market. Powerful players have entered this market, such as commercial internet search engines, information portals, multinational publishers and online content integrators. Will Google, Yahoo or Microsoft be the only portals to global knowledge in 2010? If libraries do not want to become marginalized in a key area of their traditional services, they need to acknowledge the challenges that come with the globalisation of scholarly information, the existence and further growth of the academic internet

From a user point of view this strategic support is mainly implemented by high-level search functions, so-called stratagems, which provide functionality beyond today's digital libraries. Through the tight integration of stratagems and with the federation of heterogeneous digital libraries, DAFFODIL reaches high effects of synergy for information and services. These effects provide high-quality metadata for the searcher through an intuitively controllable user interface. The implementation of stratagems follows a tool-based model.

    Abstract
    The Alexandria Digital Library (ADL) was established in the late 1990s as a response to several perceived problems of traditional map libraries, notably access and organization. By 1999 it had evolved into an operational digital library, offering a well-defined set of services to a broad user community, based on an extensive collection of georeferenced information objects. The vision of ADL continues to evolve, as technology makes new services possible, as its users become more sophisticated and demanding, and as the broader field of geographic information science (GIScience) identifies new avenues for research and application.

    Abstract
    Grounded on a strong belief that ontologies enhance the performance of information retrieval systems, there has been an upsurge of interest in ontologies. Its importance is identified in diverse research fields such as knowledge engineering, knowledge representation, qualitative modeling, language engineering, database design, information integration, object-oriented analysis, information retrieval and extraction, knowledge management and agent-based systems design (Guarino, 1998). While the role-played by ontologies, automatically lends a place of legitimacy for these tools, research in this area gains greater significance in the wake of various challenges faced in the contemporary digital environment. With the objective of overcoming various pitfalls associated with current search mechanisms, ontologies are increasingly used for developing efficient information retrieval systems. An indicator of research interest in the area of ontology is the Swoogle, a search engine for Semantic Web documents, terms and data found on the Web (Ding, Li et al, 2004). Given the complex nature of the digital content archived in digital libraries, ontologies can be employed for designing efficient forms of information retrieval in digital libraries. Knowledge representation assumes greater significance due to its crucial role in ontology development. These systems aid in developing intelligent information systems, wherein the notion of intelligence implies the ability of the system to find implicit consequences of its explicitly represented knowledge (Baader and Nutt, 2003). Knowledge representation formalisms such as 'Description Logics' are used to obtain explicit knowledge representation of the subject domain. These representations are developed into ontologies, which are used for developing intelligent information systems. Against this backdrop, the paper examines the use of Description Logics for conceptually modeling a chosen domain, which would be utilized for developing domain ontologies. The knowledge representation languages identified for this purpose are Web Ontology Language (OWL) and KArlsruhe ONtology (KAON) language. Drawing upon the various technical constructs in developing ontology-based information systems, the paper explains the working of the prototypes and also presents a comparative study of the two prototypes.

    Abstract
    From a quantitative and qualitative point of view the ETH Library is offering its users an extensive choice of information services. In this respect all researchers, all scientists and also all students have access to nearly all relevant information. This is one side of the coin. On the other hand, this broad, but also heterogeneous bundle of information sources has disadvantages, which should not be underestimated: The more information services and information channels you have, the more complex is it to find what you want to get for your scientific work. A portal-like integration of all the different information resources is still missing. The vision, the main goal of the project "Knowledge Portal" is, to develop a central access system in terms of a "single-point-of-access" for all electronic information services. This means, that all these sources - from the library's catalogue and the fulltext inhouse applications to external, licensed sources - should be accessible via one central Web service. Although the primary target group for this vision is the science community of the ETH Zurich, the interested public should also be taken into account, for the library has also a nation-wide responsibility.The general idea to launch a complex project like that comes from a survey the library did one and a half years ago. We asked a defined sample of scientists what they expected to get from their library and one constant answer was, that they wanted to have one point of access to all the electronic library services and besides this, the search processes should be as simple as possible. We accepted this demand as an order to develop a "single-point-of-access" to all electronic services the library provides. The presentation gives an overview about the general idea of the project and describes the current status.

    Abstract
    PhysNet offers online services that enable a physicist to keep in touch with the worldwide physics community and to receive all information he or she may need. In addition to being of great value to physicists, these services are practical examples of the use of modern methods of digital libraries, in particular the use of metadata harvesting. One service is PhysDoc. This consists of a Harvest-based online information broker- and gatherer-network, which harvests information from the local web-servers of professional physics institutions worldwide (mostly in Europe and USA so far). PhysDoc focuses on scientific information posted by the individual scientist at his local server, such as documents, publications, reports, publication lists, and lists of links to documents. All rights are reserved for the authors who are responsible for the content and quality of their documents. PhysDis is an analogous service but specifically for university theses, with their dual requirements of examination work and publication. The strategy is to select high quality sites containing metadata. We report here on the present status of PhysNet, our experience in operating it, and the development of its usage. To continuously involve authors, research groups, and national societies is considered crucial for a future stable service.

    Abstract
    This article describes two approaches for searching heterogeneous resources, which are explained as they are used in two corresponding existing systems-RIRS (Resource Integration Retrieval System) and HRUSP (Heterogeneous Resource Union Search Platform). On analyzing the existing systems, a possible framework-the MUSP (Multimetadata-Based Union Search Platform) is presented. Libraries now face a dilemma. On one hand, libraries subscribe to many types of database retrieval systems that are produced by various providers. The libraries build their data and information systems independently. This results in highly heterogeneous and distributed systems at the technical level (e.g., different operating systems and user interfaces) and at the conceptual level (e.g., the same objects are named using different terms). On the other hand, end users want to access all these heterogeneous data via a union interface, without having to know the structure of each information system or the different retrieval methods used by the systems. Libraries must achieve a harmony between information providers and users. In order to bridge the gap between the service providers and the users, it would seem that all source databases would need to be rebuilt according to a uniform data structure and query language, but this seems impossible. Fortunately, however, libraries and information and technology providers are now making an effort to find a middle course that meets the requirements of both data providers and users. They are doing this through resource integration.
