Abstract
Die Frage der Zuverlässigkeit und Vertrauenswürdigkeit von Webressourcen ist nicht gerade ein neues Thema - seit das World Wide Web breite Anwendung findet, ist eine Fülle an Literatur zur Bewertung von Internetquellen erschienen, die zumeist mehr oderweniger umfassende Checklisten beinhalten (vgl. z.B. Skov 1998: 40; eine sehr gute Zusammenstellung bietet Tyburski 2006). In diesem Aufsatz wird der Schwerpunkt auf Aspekte der Identität, Aktualität und inhaltlichen Qualität gelegt- dies sind die wesentlichsten Einflussfaktoren für die Bewertung der Vertrauenswürdigkeit und Seriosität von Webressourcen. Andere Kriterien wie z.B. Webdesign werden nur behandelt, sofern sie Rückschlüsse auf die oben genannten Aspekte geben können. Nach wie vor ist es so, dass gedruckte Quellen im wissenschaftlichen bzw. bildungsbezogenen Kontext als tendenziell seriöser und zuverlässiger angesehen werden als freie Webressourcen - diesen haftet der Geruch des Oberflächlichen, Beliebigen und Schnelllebigen an. Die traditionelle Bevorzugung der gedruckten bzw. lizenzierten elektronischen Ressourcen im akademischen Umfeld mag nun zwar dem traditionellen Selbstverständnis der Bibliothekarinnen durchaus gelegen kommen - allerdings besteht die Gefahr, dass Bibliotheken und ihre Informationsexpertinnen an Glaubwürdigkeit verlieren, wenn sie das World Wide Web als Ressource für hochqualitative Informationen ignorieren, ist es doch für viele Informationsbedarfe unbestritten die bessere Quelle. Grundvoraussetzung ist allerdings, durch effektive Evaluierungstechniken die Spreu vom Weizen zu trennen (vgl. Notess 2006: 45). Bibliothekarinnen haben die Expertise, mit unterschiedlichsten (gedruckten) Quellen umzugehen, für die Benutzung aufzubereiten und zugänglich zu machen. Die damit verbundene Auswahl nach Qualitätskriterien und die richtige und einheitliche Beschreibung mit Metadaten sind Kernkompetenzen des Bibliothekswesens. Wenn nun die Informationsumim Web befinden, so liegt es auf der Hand, dass ein zeitgemäßes Bibliothekswesen mit dieser Entwicklung Schritt halten muss: die Ansprüche an das Berufsbild sind deshalb starken Veränderungen unterworfen. Die organisch gewachsene, tendenziell unstrukturierte und chaotische Struktur des Webs erhöht dabei die Anforderung an eine inhaltliche Evaluation von Webressourcen. Gleichzeitig zeigt sich im bibliothekarischen Alltag, dass Leserinnen bei ihrer Webrecherche vielfach Probleme haben, diese Bewertungsleistung zu erbringen. Es gibt also einen großen Bedarf nach Vermittlung von Informations- und Internetkompetenz in Bibliotheken (vgl. Fritch und Cromwell 2002: 242f.). Schließlich weisen auch die "klassischen" bibliothekarischen Tätigkeitsbereiche immer mehr Verbindungen mit Webanwendungen auf. Hier sind beispielsweise die Katalogisierung von elektronischen Fachinformationen oder Links auf elektronische Äquivalente zu gedruckten Quellen in Katalogen zu nennen. Auch da ergeben sich fallweise Notwendigkeiten, die Aktualität und Identität von Webressourcen zu bewerten, vor allem als Grundlage für die Entscheidung, sie in den Katalog oder in eine Linksammlung überhaupt aufzunehmen.
