Abstract
Dieser Aufsatz beschreibt die Probleme bei der Erschließung des wissenschaftlichen Web (Academic Invisible Web), zeigt Beispiele kommerzieller Wissenschaftssuchmaschinen unter der Leitfrage, was Bibliotheken von diesen lernen können und stellt schließlich Vor- und Nachteile der Wissenschaftssuchmaschinen denen der bisherigen Bibliotheksangebote gegenüber. Daraus werden Empfehlungen abgeleitet, wie sich Bibliotheken mit umfassenden Suchlösungen gegenüber den Wissenschaftssuchmaschinen positionieren können.
