    Abstract
    Der Aufbau der Europäischen Digitalen Bibliothek wurde im Herbst 2007 auf soliden Grund gestellt: Mit der European Digital Library Foundation steht eine geschäftsfähige Organisation als Trägerin der Europäischen Digitalen Bibliothek zur Verfügung. Sie fungiert zunächst als Steuerungsgremium für das EU-finanzierte Projekt EDLnet und übernimmt sukzessive die Aufgaben, die für den Aufbau und die Weiterentwicklung der Europäischen Digitalen Bibliothek notwendig sind. Die Gründungsmitglieder sind zehn europäische Dachorganisationen aus den Bereichen Bibliothek, Archiv, audiovisuelle Sammlungen und Museen. Vorstandsmitglieder sind die Vorsitzende Elisabeth Niggemann (CENL) die Vize-Vorsitzende Martine de Boisdeffre (EURBICA), der Schatzmeister Edwin van Huis (FIAT) sowie Wim van Drimmelen, der Generaldirektor der Koninklijke Bibliotheek, der Nationalbibliothek der Niederlande, welche die Europäische Digitale Bibliothek hostet. Der Prototyp für die Europäische Digitale Bibliothek wird im Rahmen des EDLnet-Projekts entwickelt. Die erste Version des Prototyps wurde auf der internationalen Konferenz »One more step towards the European Digital Library« vorgestellt, die am 31. Januar und 1. Februar 2008 in der Deutschen Nationalbibliothek (DNB) in Frankfurt am Main stattfand. Die endgültige Version des Prototyps wird im November 2008 von der EU-Kommissarin für Informationsgesellschaft und Medien, Viviane Reding, in Paris vorgestellt werden. Dieser Prototyp wird direkten Zugang zu mindestens zwei Mio. digitalisierten Büchern, Fotografien, Karten, Tonaufzeichnungen, Filmaufnahmen und Archivalien aus Bibliotheken, Archiven, audiovisuellen Sammlungen und Museen Europas bieten.
    Content
    Darin u.a. "Interoperabilität als Kernstück - Technische und semantische Interoperabilität bilden somit das Kernstück für das Funktionieren der Europäischen Digitalen Bibliothek. Doch bevor Wege gefunden werden können, wie etwas funktionieren kann, muss zunächst einmal festgelegt werden, was funktionieren soll. Hierfür sind die Nutzeranforderungen das Maß aller Dinge, weshalb sich ein ganzes Arbeitspaket in EDLnet mit der Nutzersicht, den Nutzeranforderungen und der Nutzbarkeit der Europäischen Digitalen Bibliothek befasst, Anforderungen formuliert und diese im Arbeitspaket »Interoperabilität« umgesetzt werden. Für die Entscheidung, welche Inhalte wie präsentiert werden, sind jedoch nicht allein technische und semantische Fragestellungen zu klären, sondern auch ein Geschäftsmodell zu entwickeln, das festlegt, was die beteiligten Institutionen und Organisationen in welcher Form zu welchen Bedingungen zur Europäischen Digitalen Bibliothek beitragen. Auch das Geschäftsmodell wird Auswirkungen auf technische und semantische Interoperabilität haben und liefert die daraus abgeleiteten Anforderungen zur Umsetzung an das entsprechende Arbeitspaket. Im EDLnet-Projekt ist somit ein ständiger Arbeitskreislauf installiert, in welchem die Anforderungen an die Europäische Digitale Bibliothek formuliert, an das Interoperabilitäts-Arbeitspaket weitergegeben und dort umgesetzt werden. Diese Lösung wird wiederum an die Arbeitspakete »Nutzersicht« und »Geschäftsmodell« zurückgemeldet, getestet, kommentiert und für die Kommentare wiederum technische Lösungen gesucht. Dies ist eine Form des »rapid prototyping«, das hier zur Anwendung kommt, d. h. die Funktionalitäten werden schrittweise gemäß des Feedbacks der zukünftigen Nutzer sowie der Projektpartner erweitert und gleichzeitig wird der Prototyp stets lauffähig gehalten und bis zur Produktreife weiterentwickelt. Hierdurch verspricht man sich ein schnelles Ergebnis bei geringem Risiko einer Fehlentwicklung durch das ständige Feedback."

    Abstract
    Die »Düsseldorfer Virtuelle Bibliothek« (DVB) war nicht nur die erste, sondern in den Neunzigerjahren des vergangenen Jahrhunderts auch die größte wissenschaftliche virtuelle Universalbibliothek im deutschsprachigen Internet. Die beim Aufbau und der Pflege gesammelten Erfahrungen könnten auch für die derzeit entstehenden Virtuellen Fachbibliotheken von Nutzen sein, wie Thomas Hilberer im folgenden Beitrag erklärt.

    Abstract
    The following describes a number of technologies and exemplary service designs that foster better Internet finding tools in libraries and more cooperative and efficient effort in Internet resource collection building. Our library and partner institutions have been involved in this work for over a decade. The open source software and projects discussed represent appropriate technologies and sustainable strategies that will help Internet portals, digital libraries, virtual libraries and library catalogs-with-portal-like-capabilities (IPDVLCs) to scale better and to anticipate and meet the needs of scholarly and educational users.

    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    The German Internet Clearinghouse SocioGuide has changed to a database management system. Accordingly the metadata description scheme has become more detailed. The main information types are: institutions, persons, literature, tools, data sets, objects, topics, processes and services. Some of the description elements, such as title, resource identifier, and creator are universal, whereas others, such as primary/secondary information, and availability are specific to information type and cannot be generalized by referring to Dublin Core elements. The quality of Internet sources is indicated implicitly by characteristics, such as extent, restriction, or status. The SocioGuide is managed in DBClear, a generic system that can be adapted to different source types. It makes distributed input possible and contains workflow components.

    Abstract
    The current subject gateways have evolved over time when the discipline of Internet resource discovery was in its infancy. This is reflected by the lack of well-established, light-weight, deployable, easy-to-use, standards for metadata and information retrieval. We provide an introduction to the architecture, standards and software solutions in use by subject gateways, and to the issues that must be addressed to support future subject gateways

    Abstract
    Purpose - To investigate ways of demonstrating how portal implementations positively alter user information retrieval behaviour. Design/methodology/approach - An opinion piece reflecting on existing evidence about the nature of portal implementations, which extrapolates trends in user behaviour on the basis of these reflections. Findings - Although portal technologies probably do offer a way for libraries to create information tools that can compete with "one-stop shop" Internet search engines, there are likely difficulties in their pattern of usage which will have to be detected by effective quality measurement techniques. Research limitations/implications - An expression of opinion about the possible pitfalls of using portals to optimise users' information retrieval activity. Practical implications - This opinion piece gives some clear and practical guidelines for the evaluation of the success of library portal implementations. Originality/value - This editorial points out that, because the portal can be defined as a deliberate clone of a typical successful Internet search engine and may be presented to the naïve user in the same terms, the danger is that library portals might also clone the same information habits as Internet search engines, because of their ease of use. In trying to produce a tool that can meet Google on its own terms but with better content, we might reproduce some of the same educational disbenefits as Google: quality information retrieval is not purely a function of content, it is also a function of the user's perceptions and information habits.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    Clearinghouses - or subject gateways - are domain-specific collections of links to resources an the Internet. The links are described with metadata and structured according to a domain-specific subject hierarchy. Users access the information by searching in the metadata or by browsing the subject hierarchy. The standards for metadata vary across existing Clearinghouses and different technologies for storing and accessing the metadata are used. This makes it difficult to distribute the editorial or administrative work involved in maintaining a clearinghouse, or to exchange information with other systems. DBClear is a generic, platform-independent clearinghouse system, whose metadata schema can be adapted to different standards. The data is stored in a relational database. It includes a workflow component to Support distributed maintenance and automation modules for link checking and metadata extraction. The presentation of the clearinghouse an the Web can be modified to allow seamless integration into existing web sites.

    "Die Nationalbibliotheken von Dänemark, Estland und Lettland haben mit Jahresbeginn den Teilnehmerkreis von »The European Library« (www.europeanlibrary.com) erweitert. Mit der Weiterentwicklung der Portalsoftware ist das Angebot schneller und zuverlässiger geworden. Die unter dem Namen "The Europcan Library," (TEL) im Spätherbst vergangenen Jahres gestartete Europäische Digitale Bibliothek wächst weiter. Bis Ende 2006 werden die Onlinekataloge und mehr als 200 Sammlungen von 2,3 europäischen Nationalbibliotheken über dieses Internetportal recherchierbar sein. Das Angebot wird sich damit innerhalb eines Jahres nahezu verdoppeln. The European library ermöglicht integrierte Suchanfragen über institutionelle und geografische Grenzen hinweg. Das in den umfangreichen Datenbeständen der Bibliotheken repräntierte kuIturelle Erbe Europas wird damit vom Schreibtisch aus zugänglich. Urheberrechtsfreie digitale Dokumente können direkt abgerufen werden. Teilnehmende Bibliotheken passen ihre Kataloge an die Metadaten- und Suchstandards der Europäischen Digitalen Bibliothek an und ermöglichen damit die katalog- und sammlurngsübergreifende Recherche. Für The European Library wurde eine neue Webtechnologie verwendet, mit der Portalfunktionen einfach und preiswert realisiert werden können. Die Software "Portal-in-the-Browser" (www.dlib.org/dlib/february04/vanveen/02vanveen.html) steht Interessenten frei zur Verfügung. Die Entwickler erhoffen eine Anwendung in weiteren kulturellen Bereichen und damit die mögliche Verknüpfung der verschiedenen Sektoren. Für das kommende Frühjahr ist eine Benutzerbefragung zur weiteren Verbesserung von The European library geplant."

    Abstract
    Librarians have long sought to select, evaluate, and organize information on the Internet. Efforts began with individual librarians sharing bookmark files of favorite sites and progressed to increasingly large, collaboratively produced general and subject/discipline-specific gateway Web sites or megasites. Megasites list major resources usually in a particular subject area or discipline. Library portals that review, evaluate, and sometimes rate and rank resources grew from some of these Web sites. Both megasites and portals serve as gateways to the Internet. Many portals have developed from relatively small static files into large, dynamically generated databases providing descriptive annotations of selected resources and are increasingly overseen as global projects with formal policies and procedures. Portals now provide increasingly complex and sophisticated browse and search capabilities with a multitude of access points, often including call numbers and subject headings. These are described and compared. Future trends such as increased collaboration among portals; automated location, selection, and cataloging of resources; integration of multiple resource types; and increased access to full-content and virtual library services are also discussed.

    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
