    Abstract
    The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

    "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."

    Content
    Neben die Pflege der Standards tritt als Herausforderung die Vernetzung der Systeme, um heterogene Dokumentenbestände zu verbinden. »Standardisierung muss von der verbleibenden Heterogenität her gedacht werden«." Diese Aufgaben können nur in Kooperation von Bibliotheken und Informationseinrichtungen gelöst werden. Die vorgestellten Projekte zeigen, wie dies gelingen kann. Sie verfolgen alle das Ziel, Informationen über Inhalte schneller und besser für die Nutzer zur Verfügung zu stellen. Fachliche Recherchen über mehrere Informationsanbieter werden durch die Heterogenität überwindende Suchdienste ermöglicht. Die Einführung der DDC im deutschen Sprachraum steht genau im Kern des Spannungsfeldes. Die DDC stellt durch ihren universalen Charakter nicht nur einen übergreifenden Standard her. Ihre Anwendung ist nur nutzbringend, wenn zugleich die Vernetzung mit den in Deutschland bewährten Klassifikationen und Thesauri erfolgt. Ziel des Projektes DDC Deutsch ist nicht nur eine Übersetzung ins Deutsche, die DDC soll auch in Form elektronischer Dienste zur Verfügung gestellt werden. Dr. Lars Svensson, Deutsche Bibliothek Frankfurt am Main, präsentierte anschaulichdie Möglichkeiten einer intelligenten Navigation über die DDC. Für die Dokumentenbestände Der Deutschen Bibliothek, des Gemeinsamen Bibliotheksverbundes (GBV) und der Niedersächsischen Staats- und Universitätsbibliothek Göttingen wurde prototypisch ein Webservice realisiert.
