Abstract
In jüngerer Zeit wird immer häufiger die »Ein-Klick-Mentalität« der Unkundigen kritisiert und auf die wesentlichen besseren Suchergebnisse verwiesen, die Kundige mit Digitalen Bibliotheken und Metasuchen erzielen können. Ein Ausweg könnte die Strategie sein, sich diese Ein-Klick-Mentalität zunutze zu machen und die Unkundigen über Google und Co. zu den »teuren Schätzen«, den elektronischen Inhalten und Hinweisen zur wissenschaftlichen Literatur, zu führen.

Kommentar der Redaktion: "Schon heute sind große Bereiche des Internet über Suchmaschinen nicht recherchierbar, obwohl die betreffenden Angebote relevante und aktuelle Informationen enthalten können. Bei diesen für Suchmaschinen »unsichtbaren« Inhalten im so genannten Deep Web handelt es sich in der Regel um dynamische Seiten, die erst durch konkrete Anfragen eines Internetnutzers erzeugt werden. Die dabei meist aus Datenbanken abgerufenen Informationen (zum Beispiel Fahrpläne, viele Warenkataloge oder bibliographische Bestandsnachweise) sind nur temporär und ausschließlich für den Anfragenden im Internet verfügbar. Die übrige Zeit bleiben die Informationen für Suchmaschinen wie Google oder Alltheweb »verborgen« (aus diesem Grund wird das Deep Web auch als Invisible Web bezeichnet), oder ihre Erschließung wäre für die Suchmaschinenbetreiber zu aufwendig. Auch die vom Hochschulbibliothekszentrum Nordrhein Westfalen (www. hbz-nrw.de) vorgehaltenen bibliographischen Informationen und Bestandsnachweise konnten bislang im Internet nur über die Schnittstelle der Datenbank recherchiert werden. Das HBZ hat sich mit dem Angebot des Virtuellen Bücherregals NRW zum Ziel gesetzt, die in der HBZ-Verbunddatenbank abgelegten Informationen für die gängigen Internetsuchmaschinen »sichtbar« zu machen. Der vorliegende Beitrag erläutert ausführlich, wie die Titeldaten in separate HTMLSeite überführt wurden. Und er gibt vor allem eine Antwort auf die spannende Frage, ob die Suchmaschinen diesen »Köder« auch wirklich geschluckt und infolgedessen neue Kundschaft zum HBZ geführt haben." (rei)
