    Abstract
    This article reports on a model and patterns of use of a library catalog that can be accessed through the Internet. Three categories of users are identified. individuals who perform a search of the catalog, tourists who look only at opening pages of the library catalog's site, and Web spiders that come to the site to obtain pages for indexing the Web. A number of types of use activities are also identified, and can be grouped with the presearch phase (which takes place before any searching begins): the search phase, the display phase (in which users display the results of their search), and phases in which users make errors, ask the system for help or assistance, and take other actions. An empirical investigation of patterns of use of a university Web-based library catalog was conducted for 479 days. During that period, the characteristics of about 2.5 million sessions were recorded and analyzed, and usage trends were identified. Of the total, 62% of the sessions were for users who performed a search, 27% were from spiders, and 11% were for tourists. During the study period, the average search session lasted about 5 minutes when the study began and had increased to about 10 minutes 16 months later. An average search consisted of about 1.5 presearch actions lasting about 25 seconds, about 5.3 display actions, and 2.5 searches per session. The latter two categories are in the range of 35-37 seconds per session each. There were major differences in usage (number of searches, search time, number of display actions, and display time), depending upon the database accessed

    Abstract
    Recherche in Bibliothekskatalogen war, zumindest in deutschen Bibliotheken, bis zur Mitte des 20. Jahrhunderts in der Regel Sache des Personals, eine wirklich erfolgreiche Recherche meist Spezialisten vorbehalten. Nur diese waren in der Lage, häufig unter Einbeziehung diverser Hilfsmittel, Titelwünsche der Leser nach den jeweiligen Katalog- und Bibliotheksregeln in entsprechende Kataloganfragen umzusetzen. Als dann den Bibliothekskunden selbst nach und nach der Zugang zu diesen Zettelkatalogen in den Bibliotheken eröffnet wurde, war für eine erfolgreiche Suche meist "guter Rat teuer". Hilfestellung und "guter Rat", oft schon bei einer simplen Titelsuche wie "Schuld und Sühne" nötig, konnte vom uneingeweihten Leser direkt vor Ort in der Bibliothek eingeholt werden. Elektronische Formen der Kataloge in Bibliotheken, kurz "OPACs" genannt, eröffneten neue, den alten Zettel- und Mikrofichekatalogen völlig unbekannte Suchmöglichkeiten. Sie zogen aber auch neue Fragestellungen nach sich, besonders zum Handling und zur Suchstrategie. Zumindest dem "fragemutigen" Nutzer konnte und kann dabei vor Ort in den Bibliotheken immer noch direkt geholfen werden. Diese Hilfestellung entfällt jedoch bei allen Bibliotheks- und Verbundkatalogen, die im Internet als so genannte "Web-OPACs" angeboten werden. Sie erreichen einen viel größeren, dafür aber anonym bleibenden Interessentenkreis, vom absoluten Bibliothekslaien bis zum kundigen Bibliotheksnutzer. Diese aktiven und potentiellen Nutzer treten mit den unterschiedlichsten Anforderungen und Fragestellungen an solche Web-OPACs heran. Ein Web-OPAC muss demnach so gestaltet sein, dass er für Laien und Profis gleichermaßen nutzbar ist und dabei möglichst wenige Fragen überhaupt erst aufkommen lässt, im Idealfall also über eine selbsterklärende Oberfläche verfügt. Hilfetexte müssen die nicht vorhandene persönliche Hilfestellung kompensieren helfen. Sie sind also übersichtlich, verständlich und zielgerichtet einsetzbar zu gestalten.
