    Für viele Wissenschaftler ist das Internet nach wie vor Fluch und Segen zugleich - unzählige Informationen, aber kaum ein sachgerechter, selektiver Zugriff auf validierte Quellen. Überfällig sind deshalb Dienste, die der hohen Qualitätsanforderung und Erwartungshaltung der Wissenschaft an die Webrecherche gerecht werden. Im Prinzip gibt es derzeit zwei konkurrierende Strategien zur Lösung dieses Problems. Suchmaschinenanbieter versuchen dem täglich wachsenden Informationsangebot im Internet mit immer ausgeklügelteren Suchtechnologien zu begegnen und liefern in vielen Fällen auch sehr gute Ergebnisse. Für die fachwissenschaftliche Recherche sind Suchmaschinen jedoch nicht in jedem Fall die erste Wahl. Insbesondere bei einem thematischen Sucheinstieg liefern Suchmaschinen unbefriedigende Treffer. Zu nennen sind hier schlagwortartig u.a. zu große Treffermengen, mangelnde Authentizität oder eine nicht nachprüfbare Verlässlichkeit der Quellen. Zudem wird auch das "Deep Web" von den Suchmaschinen nicht oder nur schwer erreicht. Die wissenschaftlichen Bibliotheken dagegen setzten bislang auf das Prinzip der intellektuellen Auswahl, Katalogisierung und Beschreibung fachlich relevanter Internetquellen. Im Kontext der Virtuellen Fachbibliotheken werden umfangreiche Linksammlungen aufgebaut, den so genannten Fachinformationsführern oder auch den "quality controlled subject gateways", in denen i.d.R. ausschließlich fachlich relevante Quellen nachgewiesen werden. Doch die Zahl der nachgewiesenen Quellen bewegt sich meist im tausenderbereich und ruft Kritiker auf den Plan, die nicht gänzlich unbegründet die Frage nach der Sinnhaftigkeit stellen, das Web mit bibliothekarischen Mitteln katalogisieren zu wollen. Diese Kritik zeigt deutlich die Grenzen von Fachinformationsführern auf, die von vielen übersehen werden. Ein Fachinformationsführer kann allenfalls den Zugang zu den zentralen Einstiegspunkten bieten. Der besondere Mehrwert liegt darin, dass die Nutzer ausschließlich Quellen findet, die einen strengen Auswahlprozess durchlaufen haben und über einen thematischen Zugang (Browsing) erreichbar sind. Was fehlt ist ein Zugang zu einem fachwissenschaftlichen Websuchraum, in dem ausschließlich fachlich relevante Quellen - auch aus dem "Deep Web" zu finden sind. Für die Virtuelle Fachbibliothek Politikwissenschaft (ViFaPol) konnte diese Lücke durch eine Kooperation mit dem Suchmaschinenanbieter Seekport lnternet Techno-logies (www.seekport.de) geschlossen werden. Seekport realisiert auf der Basis der ca. 3.800 Quellen, die im Fachinformationsführer nachgewiesen sind, eine Volltextsuche in den Quellen bis zur 3. Hierarchieebene. In ViFaPol können Wissenschaftler nunmehr in einem fachlichen Websuchraum mit knapp 21/2 Millionen Seiten recherchieren, darunter mehr als 140.000 wissenschaftliche Volltexte (PDF-Dokumente). Ziel der Partnerschaft zwischen Bibliothek und Suchmaschinenanbieter ist die Zusammenführung des Besten aus beiden Welten ist das Ziel der Partnerschaft von Bibliothek und Suchmaschinenanbieter - ein Beispiel, das Schule machen könnte."

    Die für die Informationsgesellschaft und die Medien zuständige EU-Kommissarin Viviane Reding sagte: »Europeana ermöglicht eine Reise über Zeiten und Grenzen hinweg und regt zu neuen Gedanken darüber an, was unsere Kultur ausmacht. Mehr noch: sie verbindet Menschen mit ihrer Geschichte und - über interaktive Seiten und Werkzeuge - miteinander. Ich rufe nun alle europäischen Kulturinstitutionen, Verlage und Technologieunternehmen auf, Europeana mit weiteren digitalen Inhalten zu füllen. Europeana sollte allen Menschen die Gelegenheit bieten, interaktiv und kreativ ihr eigenes Stück europäischer Kultur zu schaffen und es mit anderen zu teilen. Mein Ziel ist, dass Europeana im Jahr 2010 mindestens 10 Millionen Objekte enthält.« Elisabeth Niggemann, Generaldirektorin der Deutschen Nationalbibliothek und Vorsitzende der European Digital Library Foundation (der Organisation hinter Europeana), fügte hinzu: »Durch Europeana werden kulturelle Einrichtungen interessanter für die Generation Web 2.0 - eine Generation, die zur gleichen Zeit am gleichen Ort Texte lesen, Videos sehen, Laute hören und Bilder sehen möchte. Dieses vollständige Multimediaangebot bringtjungen Menschen Europas Kultur, Vergangenheit und Zukunft näher.« Europeana ermöglicht es, die digitalisierten Sammlungen europäischer Bibliotheken, Archive und Museen gleichzeitig zu durchsuchen, d. h. die Nutzer können Themen erforschen, ohne eine Vielzahl von Internetseiten besuchen oder durchsuchen zu müssen. Im Jahr 2005 von der Europäischen Kommission initiiert, wurde Europeana in enger Zusammenarbeit der Nationalbibliotheken und anderer kultureller Einrichtungen der Mitgliedstaaten sowie mit nachdrücklicher Unterstützung des Europäischen Parlaments aufgebaut. Europeana wird von der European Digital Library Foundation betrieben, in der sich die wichtigsten europäischen Verbände von Bibliotheken,Archiven, Museen, audiovisuellen Archiven und kulturellen Einrichtungen zusammengeschlossen haben. Verwaltet wird Europeana von der niederländischen Nationalbibliothek, der Koninklijke Bibliotheek. Über -.000 Kulturorganisationen aus ganz Europa, etwa der Louvre in Paris und das Rijksmuseum in Amsterdam, haben Material, z. B. digitalisierte Gemälde und Objekte aus ihren Sammlungen, für Europeana bereitgestellt. Wichtige nationale Dokumente aus Staatsarchiven sind verfügbar und das Institut National de l'Audiovisuel (Frankreich) hat 80.000 Rundfunksendungen geliefert, die das gesamte 2o.Jahrhundert abdecken, angefangen mit einer Übertragung von den französischen Schlachtfeldern aus dem Jahr 1914. Nationalbibliotheken aus ganz Europa haben ferner gedrucktes und handschriftliches Material beigesteuert, darunter digitalisierte Kopien der »großen« Bücher, die der Welt neue Ideen geschenkt haben.

    Abstract
    The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program comprises a set of projects engaged in a collective effort to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational materials for students and teachers at all levels, in both formal and informal settings. By providing broad access to a rich, reliable, and authoritative collection of interactive learning and teaching resources and associated services in a digital environment, the NSDL will encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning. Though the program is relatively new, its vision and operational framework have been developed over a number of years through various workshops and planning meetings. The NSDL program held its first formal funding cycle during fiscal year 2000 (FY00), accepting proposals in four tracks: Core Integration System, Collections, Services, and Targeted Research. Twenty-nine awards were made across these tracks in September 2000. Brief descriptions of each FY00 project appeared in an October 2000 D-Lib Magazine article; full abstracts are available from the Awards Section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. In FY01 the program received one hundred-nine proposals across its four tracks with the number of proposals in the collections, services, and targeted research tracks increasing to one hundred-one from the eighty received in FY00. In September 2001 grants were awarded to support 35 new projects: 1 project in the core integration track, 18 projects in the collections track, 13 in the services track, and 3 in targeted research. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) are both providing significant co-funding on several projects, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. Thus far across both fiscal years of the program fifteen projects have enjoyed this joint support. Following is a list of the FY01 awards indicating the official NSF award number (each beginning with DUE), the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the Awards Section at the NSDL program site at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. (Grants with shared titles are formal collaborations and are grouped together.) The projects are displayed by track and are listed by award number. In addition, six of these projects have explicit relevance and application to K-12 education. Six others clearly have potential for application to the K-12 arena. The NSDL program will have another funding cycle in fiscal year 2002 with the next program solicitation expected to be available in January 2002, and an anticipated deadline for proposals in mid-April 2002.

    Abstract
    Reference services have taken a central place in library and information services. They are also regarded as personalised services since in most cases a personal discussion takes place between a user and a reference librarian. Based on this, the librarian points to the sources that are considered to be most appropriate to meet the specific information need(s) of the user. Since the Web and digital libraries are meant for providing direct access to information sources and services without the intervention of human intermediaries, the pertinent question that appears is whether we need reference services in digital libraries, and, if so, how best to offer such services. Current digital libraries focus more on access to, and retrieval of, digital information, and hardly lay emphasis on the service aspects. This may have been caused by the narrower definitions of digital libraries formulated by digital library researchers. This paper looks at the current state of research in personalised information services in digital libraries. It first analyses some representative definitions of digital libraries in order to establish the need for personalised services. It then provides a brief overview of the various online reference and information services currently available on the Web. The paper also briefly reviews digital library research that specifically focuses on the personalisation of digital libraries and the provision of digital reference and information services. Finally, the paper proposes some new areas of research that may be undertaken to improve the provision of personalised information services in digital libraries.

    Abstract
    Do a search on AltaVista for "algebra". What do you get? Nearly 700,000 hits, of which AltaVista will allow you to view only what it determines is the top 200. Major search engines such as AltaVista, Excite, HotBot, Lycos, and the like continue to provide a valuable service, but with the recent growth of the Internet, topic-specific sites that provide some organization to the topic are increasingly important. It the goal of the Mathematics Archives to make it easier for the ordinary user to find useful mathematical information on the Web. The Mathematics Archives (http://archives.math.utk.edu) is a multipurpose site for mathematics on the Internet. The focus is on materials which can be used in mathematics education (primarily at the undergraduate level). Resources available range from shareware and public domain software to electronic proceedings of various conferences, to an extensive collection of annotated links to other mathematical sites. All materials on the Archives are categorized and cross referenced for the convenience of the user. Several search mechanisms are provided. The Harvest search engine is implemented to provide a full text search of most of the pages on the Archives. The software we house and our list of annotated links to mathematical sites are both categorized by subject matter. Each of these collections has a specialized search engine to assist the user in locating desired material. Services at the Mathematics Archives are divided up into five broad topics: * Links organized by Mathematical Topics * Software * Teaching Materials * Other Math Archives Features * Other Links

    Abstract
    Purpose - The purpose of this paper is to report an investigation into the ways in which Canadian digital library collections have incorporated knowledge organization systems into their search interfaces. Design/methodology/approach - A combination of data-gathering techniques was used. These were as follows: a review of the literature related to the application of knowledge organization systems, deep scanning of Canadian governmental and academic institutions web sites on the web, identify and contact researchers in the area of knowledge organization, and identify and contact people in the governmental organizations who are involved in knowledge organization and information management. Findings - A total of 33 digital collections were identified that have made use of some type of knowledge organization system. Thesauri, subject heading lists and classification schemes were the widely used knowledge organization systems in the surveyed Canadian digital library collections. Research limitations/implications - The target population for this research was limited to governmental and academic digital library collections. Practical implications - An evaluation of the knowledge organization systems interfaces showed that searching, browsing and navigation facilities as well as bilingual features call for improvements. Originality/value - This research contributes to the following areas: digital libraries, knowledge organization systems and services and search interface design.

    Abstract
    CORC is an OCLC project that id developing tools and systems to enable libraries to provide enhanced access to Internet resources. By adapting and extending library techniques and procedures, we are developing a self-supporting system capable of describing a large and useful subset of the Web. CORC is more a system for hosting and supporting subject gateways than a gateway itself and relies on large-scale cooperation among libraries to maintain a centralized database. By supporting emerging metadata standards such as Dublin Core and other standards such as Unicode and RDF, CORC broadens the range of libraries and librarians able to participate. Current plans are for OCLC as a full service in July 2000

    Abstract
    A preliminary, purposive survey of definitions and current applications of facet analytical theory (FA) is used to develop a framework for the analysis of Websites. This set of guidelines may well serve to highlight commonalities and differences among FA applications an the Web. Rather than identifying FA as the terrain of a particular interest group, the goal is to explore current practices, uncover common misconceptions, extend understanding, and highlight developments that augment the traditional practice of FA and faceted classification (FC).

    Abstract
    For many years metadata has been recognised as a significant component of the digital information environment. Substantial work has gone into creating complex metadata schemes for describing digital content. Yet increasingly Web search engines, and Google in particular, are the primary means of discovering and selecting digital resources, although they make little use of metadata. This article considers how digital libraries can gain more value from their metadata by adapting it for Google users, while still following well-established principles and standards for cataloguing and digital preservation.

    Abstract
    The Web, and consequently the information contained in it, is growing rapidly. Every day a huge amount of newly created information is electronically published in Digital Libraries, whose aim is to satisfy users' information needs. In this paper, we envisage a Digital Library not only as an information resource where users may submit queries to satisfy their daily information need, but also as a collaborative working and meeting space of people sharing common interests. Indeed, we will present a personalized collaborative Digital Library environment, where users may organize the information space according to their own subjective view, may build communities, may become aware of each other, may exchange information and knowledge with other users, and may get recommendations based on preference patterns of users.

    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.
