    Abstract
    This article addresses a crucial issue in the digital library environment: how to support effective interaction of users with heterogeneous and distributed information resources. In particular, this study compared usability, user preference, effectiveness, and searching behaviors in systems that implement interaction with multiple databases as if they were one (integrated interaction) in a experiment in the TREC environment. 28 volunteers were recruited from the graduate students of the School of Communication, Information & Library Studies at Rutgers University. Significantly more subjects preferred the common interface to the integrated interface, mainly because they could have more control over database selection. Subjects were also more satisfied with the results from the common interface, and performed better with the common interface than with the integrated interface. Overall, it appears that for this population, interacting with databases through a common interface is preferable on all grounds to interacting with databases through an integrated interface. These results suggest that: (1) the general assumption of the information retrieval (IR) literature that an integrated interaction is best needs to be revisited; (2) it is important to allow for more user control in the distributed environment; (3) for digital library purposes, it is important to characterize different databases to support user choice for integration; and (4) certain users prefer control over database selection while still opting for results to be merged

    Abstract
    Das Projekt CARMEN startete als Sonderfördermaßnahme im Rahmen von Global lnfo im Oktober 1999 mit einer geplanten Laufzeit von 29 Monaten. Der Schwerpunkt des Projekts liegt in der Weiterentwicklung von Konzepten und Verfahren der Dokumenterschließung, die den Zugriff auf heterogene, dezentral verteilte Informationsbestände und deren Verwaltung nach gemeinsamen Prinzipien ermöglichen sollen. Dabei geht CARMEN gezielt einen anderen Weg als die meisten bisherigen Ansätze in diesem Bereich, die versuchen, Homogenität und Konsistenz in einer dezentralen Informationslandschaft technikorientiert herzustellen, indem Verfahren entwickelt werden, durch die physikalisch auf verschiedene Dokumentenräume gleichzeitig zugegriffen werden kann. Eine rein technische Parallelisierung von Zugriffsmöglichkeiten reicht jedoch nicht aus, denn das Hauptproblem der inhaltlichen, strukturellen und konzeptionellen Differenz der einzelnen Datenbestände wird damit nicht gelöst. Um diese Differenzen zu kompensieren, werden Problemlösungen und Weiterentwicklungen innerhalb des Projekts CARMEN in drei Bereichen erarbeitet: (1) Metadaten (Dokumentbeschreibung, Retrieval, Verwaltung, Archivierung) (2) Methoden des Umgangs mit der verbleibenden Heterogenität der Datenbestände (3) Retrieval für strukturierte Dokumente mit Metadaten und heterogenen Datentypen. Diese drei Aufgabenbereiche hängen eng zusammen. Durch die Entwicklungen im Bereich der Metadaten soll einerseits die verlorengegangene Konsistenz partiell wiederhergestellt und auf eine den neuen Medien gerechte Basis gestellt werden. Andererseits sollen durch Verfahren zur Heterogenitätsbehandlung Dokumente mit unterschiedlicher Datenrelevanz und Inhaltserschließung aufeinander bezogen und retrievalseitig durch ein Rechercheverfahren erganzt werden, das den unterschiedlichen Datentypen gerecht wird Innerhalb des Gesamtprojekts CARMEN werden diese Aspekte arbeitsteilig behandelt. Acht Arbeitspakete (APs) befassen sich in Abstimmung miteinander mit je verschiedenen Schwerpunkten. Um die Koordination der Arbeiten der verschiedenen APs untereinander zu unterstützen, trafen sich die ca. 40 Projektbearbeiter am 1. und 2. Februar 2001 zum "CARMEN middle OfTheRoad Workshop" in Bonn. Anlässlich dieses Workshops wurden die inhaltlichen und technischen Ergebnisse, die in der ersten Hälfte der Projektlaufzeit von den einzelnen APs erzielt worden sind, in insgesamt 17 Präsentationen vorgestellt
