Title

"Gibt es auch Wahnsinn" : Benutzeruntersuchungen an einem Hamburger WebOPAC

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.
