- 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 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
- 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.

- Abstract
- Trotz Opac-Einführungen durch das Bibliothekspersonal treten beim Benutzer häufig Rechercheprobleme auf. Oftmals werden die Möglichkeiten, die der Opac bietet, von Benutzern nicht richtig erkannt. An der Universitätsbibliothek Tübingen gingen im Rahmen des sechsmonatigen Praxissemesters Studentinnen der Fachhochschule Stuttgart - Hochschule der Medien den Ursachen dieses Problems nach.

- Abstract
- The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

- Abstract
- An exploratory research study on OPACs was done within the framework of the French PARINFO program by four different teams: ENSSIB-CERSI, City Univ. of London, Médiathèque of the Cité des Sciences et de l'industrie and a firm GSI-ERLI. During the month of June 1992, 650 individual searches on four terminals were collected. The sessions were automatically recorded, accompanied by two online questionnaires, a pre-search and a post-search questionnaire. Some questions were asked orally by an interviewer and the answers noted. The article analyses the researches perceived by user as difficult or impossible. Some examples of the difficulties are given
