    Abstract
    Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

    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
    Der Beitrag fasst die Ergebnisse einer Untersuchung von über 50 000 Suchanfragen am Hamburger Campus-Katalog zusammen. Der Campus-Katalog ist ein WEB-Katalog auf der Basis des Pica-Lokalsystems LBS3, dessen Protokolldateien die Rohdaten lieferten. Über die statistische Analyse der Suchanfragen hinaus, wird ein Versuch unternommen, die einzelnen Schritte einer Katalogrecherche zusammenzufassen und die Reaktion der Benutzer auf erfolglose Suchanfragen zu untersuchen.
