    Abstract
    Im Rahmen eines Projektseminars am Institut für Bibliotheks- und Informationswissenschaft der Humboldt Universität zu Berlin wurden an wissenschaftlichen Bibliotheken Benutzerbefragungen durchgeführt. Wir haben die Antworten auf eine Frage zum Informationsverhalten bibliotheksübergreifend statistisch ausgewertet. Neben Unterschieden zwischen Fächern stellen wir fest, dass sich das Informationsverhalten junger Bibliotheksnutzer oft erheblich von dem älterer Nutzer unterscheidet. Das Verhalten von Bibliotheksnutzern hinsichtlich der Häufigkeit der Nutzung von Bibliotheksangeboten und dem World Wide Web (WWW) ist vorwiegend ähnlich. Nutzer mit konträrem Verhalten sind unterrepräsentiert gegenüber denen, die beides, Bibliothek und Web, oft oder beides wenig nutzen.

    Abstract
    Im Rahmen einer Überarbeitung und Erweiterung des Internet-Auftritts der Stadtbibliothek Stuttgart wurde die Bedienerfreundlichkeit (usability) des Online-Katalogs (OPAC) der Bücherei wissenschaftlich getestet, um daraus Kriterien für eine mögliche Verbesserung herauszuarbeiten. Anfragen von Nutzern der Bibliothek und Beobachtungen der Bibliotheksmitarbeiterinnen hatten in der Vergangenheit deutlich gemacht, dass es offensichtlich nicht allen Nutzern problemlos möglich ist, den Katalog effektiv und angemessen zu nutzen. Da es sich beim webbasierten Online-Katalog um das Kernstück der Website der Bibliothek handelt, hatte seine Optimierung größte Priorität. Das Ziel sollte sein, einen Katalog anzubieten, der von sämtlichen potentiellen Nutzern mit den unterschiedlichsten Vorkenntnissen mit möglichst geringem Aufwand und einem optimalen Suchergebnis bedient werden kann.

    Abstract
    Die Einführung von CD-ROM Datenbanken als neue Informationstechnologie hat die Formen der Informationsgewinnung in bestimmten wissenschaftlichen Fachgebieten grundlegend geändert. Der Beitrag berichtet über Ergebnisse wissenschaftlicher Begleitforschung bei Endnutzerrecherchen in der CD-ROM-Version der Datenbank MEDLINE. Hierzu wurden drei verschiedene Erhebungen durchgeführt. Hiernach ist die überwiegende Zahl der Endnutzer (89,3%) mit dem jeweiligen Rechercheresultat zufrieden, wobei Benutzer mit geringer Rechercheerfahrung eine höhere Zufriedenheitsrate erreichen als Benutzer mit umfangreicheren Recherchekenntnissen. Die Gründe zur Nutzung von CD-ROM-Systemen resultieren voriwegend aus der klinischen Alltagsroutine oder täglichen Forschungspraxis, während vermittelte Online-Literatursuchen tendenziell häufiger im Zusammenhang mit einmaligen Ereignissen der wissenschaftlichen Aus- und Weiterbildung stehen. Die selbständige CD-ROM Literaturrecherche stellt für die befragten Ärzte und Wissenschaftler die bevorzugte Methode der Informationsgewinnung dar. Die analysierten Endnutzerrecherchen weisen allerdings Fehler und Defizite hinsichtlich einer optimalen Suchstrategie auf, die zu unbemerktn Informationsverlusten und zu Fehlbeurteilungen des wissenschaftlichen Kenntnisstandes führen
