    Abstract
    In der Bibliothek der Universität Konstanz werden seit eineinhalb Jahren CD-ROM-Datenbanken für Endnutzerrecherchen angeboten. Der Benutzungsstatistik zufolge werden die CD-ROM-Datenbanken häufig verwendet, und die Benutzer sind mit den Ergebnissen ihrer Recherchen überwiegend zufrieden. Eien detaillierte Analyse der Protokolle von 52 recherchen zeigt jedoch, daß die Endnutzer Schwierigkeiten mit der Systembedienung haben und ihre Suchanfragen häufig unzulänglich formulieren. Konsequenzen für die Entwicklung von Schulungsprogrammen und für die Einbindung von CD-ROM-Datenbanken in das Informationsangebot wissenschaftlicher Bibliotheken werden aufgezeigt
