    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
    Nach Einführungen zu Jugend und Internet, Medienkompetenz und Lernen durch Medien, wird im praktischen Teil eine schriftliche Umfrage unter 90 Schülern eines Gymnasiums und einer Gesamtschule über deren Internetnutzung für schulische Zwecke analysiert. Suchpraxis, Einbindung des Internets in den schulischen Alltag, Unterschiede bei Geschlechtern und Schulformen werden besonders untersucht. Die Auswertung ergibt selbstbewußte Grundeinstellung der Schüler zum Internet, eher privat als schulisch genutzt, geschätzt wegen Schnelligkeit, Informationsmenge und Spaßfaktor bei Fixierung auf die Suchmaschine Google. Die Schüler geben sich meistens mit den gefundenen Ergebnissen zufrieden, stellen deren Qualität nicht weiter in Frage.

    Abstract
    Im Rahmen eines Projektseminars am Institut für Bibliotheks- und Informationswissenschaft der Humboldt Universität zu Berlin wurden an wissenschaftlichen Bibliotheken Benutzerbefragungen durchgeführt. Wir haben die Antworten auf eine Frage zum Informationsverhalten bibliotheksübergreifend statistisch ausgewertet. Neben Unterschieden zwischen Fächern stellen wir fest, dass sich das Informationsverhalten junger Bibliotheksnutzer oft erheblich von dem älterer Nutzer unterscheidet. Das Verhalten von Bibliotheksnutzern hinsichtlich der Häufigkeit der Nutzung von Bibliotheksangeboten und dem World Wide Web (WWW) ist vorwiegend ähnlich. Nutzer mit konträrem Verhalten sind unterrepräsentiert gegenüber denen, die beides, Bibliothek und Web, oft oder beides wenig nutzen.

    Abstract
    An 2 biowissenschaftlichen Einrichtungen der Grundlagenforschung, dem Max-Delbrück-Centrum für Molekulare Medizin, Berlin-Buch und dem Leibniz-Institut für Neurobiologie, Magdeburg, wurden 1997 bzw. 1998 Nutzerbefragungen durchgeführt. Obwohl die untersuchten Gruppen beträchtliche Altersunterschiede aufwiesen, ergeben sich einheitliche Trends: für etwa 2/3 der Wissenschaftler ist gegenwärtig die Nutzung von Printmedien und elektronischen Informationsofferten gleichwertig, während etwa 15% der Befragten letzteren den Vorzug geben. Bei der Datenbanknutzung ist festzustellen, daß MEDLINE die überragende Position sowohl bei der CD-ROM als auch Online im Internet einnimmt

    Abstract
    With the rapid diffusion of the Internet, researchers, policy makers, and users have raised concerns about online privacy, although few studies have integrated aspects of usage with psychological and attitudinal aspects of privacy. This study develops a model involving gender, generalized self-efficacy, psychological need for privacy, Internet use experience, Internet use fluency, and beliefs in privacy rights as potential influences on online privacy concerns. Survey responses from 413 college students were analyzed by bivariate correlations, hierarchical regression, and structural equation modeling. Regression results showed that beliefs in privacy rights and a psychological need for privacy were the main influences on online privacy concerns. The proposed structural model was not well supported by the data, but a revised model, linking self-efficacy with psychological need for privacy and indicating indirect influences of Internet experience and fluency on online privacy concerns about privacy through beliefs in privacy rights, was supported by the data.

    Abstract
    Faculty members from a major university were surveyed to explore the possible relationship between Internet usage and the following dependent variables: computer usage (length of time and perceived expertise), length of time of Internet use, perceived expertise of Internet use, and perceived utility of the Internet. 97% have an Internet account. Furthermore, computer literacy and length of computer experience are correlated with early adoption of the Internet, perceived utility of the Internet is correlated with computer literacy and with Internet usage, and usage is correlated with perceived expertise, but not with the length of time of Internet experience. Highly skilled computer users are more likely to use the network in a more intensive way and have higher appreciation of the network's potential

    Abstract
    Account of a limited experimental study at the Bibliothèque Publique d'Informations (BPI), the Paris multimedia public library, to establish a methodology for investigating user interactions with new technology. A wide range of materials are available at the BPI, including CD-ROMs and the Internet. Preliminary observations indicate that users do not follow the pattern dictated by the machine, but take approaches based on their own experience and skills. Setbacks are generally interpreted as defects in the software, not personla failure to master the system. Large scale qualitative abservation, using research methods from the social sciences, would establish a knowledge base for developing user skills to exploit multimedia resources more fully

    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
    Reports on research into the information-seeking habits of primary schoolchildren conducted under operational conditions. Three workstations with Internet access were installed in a grade-six classroom in suburban Montreal. After a short introductory training session for the entire group followed by short individual sessions for each student, 53 students, working in small groups, used these workstations over a six-week period to seek information on the Web of relevance to a class project assigned by their teacher. The project dealt with the Winter Olympic Games (recently completed at that time). The student objective was to locate relevant information for a poster and an oral presentation on one of the sports represented at the Games. All screen activity was directly captured on videotape and group conversations at the workstation were audiotaped. Demographic and computer literacy information was gathered in a questionnaire. This paper presents a map of the information-seeking landscape based upon an analysis of the descriptive statistics gathered from the Web searches. It reveals that the novice users favored browsing over analytic search strategies, although they did show some sophistication in the construction of the latter. Online help was ignored. The children demonstrated a very high level of interactivity with the interface at the expense of thinking, planning and evaluating. This is a preliminary analysis of data which will subsequently be expanded by the inclusion of qualitative data

    Abstract
    Web links have been studied by information scientists for at least six years but it is only in the past two that clear evidence has emerged to show that counts of links to scholarly Web spaces (universities and departments) can correlate significantly with research measures, giving some credence to their use for the investigation of scholarly communication. This paper reports an a study to investigate the factors that influence the creation of links to journal Web sites. An empirical approach is used: collecting data and testing for significant patterns. The specific questions addressed are whether site age and site content are inducers of links to a journal's Web site as measured by the ratio of link counts to Journal Impact Factors, two variables previously discovered to be related. A new methodology for data collection is also introduced that uses the Internet Archive to obtain an earliest known creation date for Web sites. The results show that both site age and site content are significant factors for the disciplines studied: library and information science, and law. Comparisons between the two fields also show disciplinary differences in Web site characteristics. Scholars and publishers should be particularly aware that richer content an a journal's Web site tends to generate links and thus the traffic to the site.

    Abstract
    Hypothesizing that workplace significantly affects information-seeking patterns, this study compared accessibility and use of information sources among 233 Israeli computer scientists and software engineers, employed in industry and academy, using a mail questionnaire, which yielded a usable reply rate of 33%. The two groups were found to differ significantly in age, education, seniority, and type of research they performed (basic vs. applied). Printed textbooks, professional journals, and oral discussions with colleagues or experts in the organization were common to both groups, topping almost all lists of accessibility and use. For most information sources, however, the two groups differed significantly and consistently. Printed professional journals as weIl as printed and electronic conference or meeting papers were consistently more accessible and more often used by the academy group, while the industry group reported greater access to and more frequent use of electronic textbooks and trade or promotional literature. In regard to handbooks and standards, in-house technical reports (printed), government technical reports (Internet), librarians and technical specialists (Internet), and oral discussions with supervisors, no significant differences in accessibility were found, but their use by the industry group was much higher. In both groups, accessibility was only partly related to use, and more so among the academy than the industry group.

    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.

    Abstract
    A survey of 4,032 youth in grades 5 through 12 was conducted to determine the impact youth's use of the Internet was having on their use of the public library. Results indicated that 100% of the youth had access to the Internet from one or more locations, and that although one quarter of the youth accessed the Internet at the public library, the public library was the least frequently used source of Internet access. For youth without Internet access at home, the public library was also the least used alternate source of access. Approximately 69% of the youth reported that they had visited a public library during the school year. Having Internet access at home did not affect whether or not youth visited the library however, Internet access at home appears to have affected the frequency with which youth visit the library. Youth without Internet access at home visited the library more frequently, whereas youth with Internet access at home visited the library less frequently. Use of the Internet also appeared to have diminished youth's need to use the public library as a source of personal information however, use of the Internet appeared not to have affected their use of the public library for school work or for recreation. Among youth, use of both the Internet and the public library appear to be complementary activities.
