    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
    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
    Thirty-one patrons, who were selected by Slone to provide a range of age and experience, agreed when approached while using the catalog of the Wake County library system to try searching via the Internet. Fifteen searched the Wake County online catalog in this manner and 16 searched the World Wide Web, including that catalog. They were subjected to brief pre-structured taped interviews before and after their searches and observed during the searching process resulting in a log of behaviors, comments, pages accessed, and time spent. Data were analyzed across participants and categories. Web searches were characterized as linking, URL, search engine, within a site domain, and searching a web catalog; and participants by the number of these techniques used. Four used only one, 13 used two, 11 used three, two used four, and one all five. Participant experience was characterized as never used, used search engines, browsing experience, email experience, URL experience, catalog experience, and finally chat room/newsgroup experience. Sixteen percent of the participants had never used the Internet, 71% had used search engines, 65% had browsed, 58% had used email, 39% had used URLs, 39% had used online catalogs, and 32% had used chat rooms. The catalog was normally consulted before the web, where both were used, and experience with an online catalog assists in web use. Scrolling was found to be unpopular and practiced halfheartedly.
