- Abstract
- The World Wide Web was created in 1989, but it has already become a major information channel and source, influencing our everyday lives, commercial transactions, and scientific communication, to mention just a few areas. The seventeenth-century philosopher Descartes proclaimed, "I think, therefore I am" (cogito, ergo sum). Today the Web is such an integral part of our lives that we could rephrase Descartes' statement as "I have a Web presence, therefore I am." Because many people, companies, and organizations take this notion seriously, in addition to more substantial reasons for publishing information an the Web, the number of Web pages is in the billions and growing constantly. However, it is not sufficient to have a Web presence; tools that enable users to locate Web pages are needed as well. The major tools for discovering and locating information an the Web are search engines. This review discusses the use of Web search engines in information science research. Before going into detail, we should define the terms "information science," "Web search engine," and "use" in the context of this review.

- Abstract
- Conducting a literature review is an important activity for postgraduates and many undergraduates. Librarians can play an important role, directing students to digital libraries, compiling online subject reSource lists, and educating about the need to evaluate the quality of online resources. In order to conduct an effective literature search in a new area, however, in some subjects it is necessary to gain basic topic knowledge, including specialist vocabularies. Google's link-based page ranking algorithm makes this search engine an ideal tool for finding specialist topic introductory material, particularly in computer science, and so librarians should be teaching this as part of a strategic literature review approach.

- "Nach Büchern folgen jetzt auch Zeitschriften: Google digitalisiert gedruckte Magazine und macht sie über die Buchsuche zugänglich. Möglich ist das durch eine Partnerschaft des Suchmaschinenbetreibers mit mehreren Zeitschriftenverlagen in den USA. Anders als viele von Google digitalisierte Bücher können die Zeitschriftenartikel auch in Deutschland gelesen werden. Unter den Magazinen finden sich zum Beispiel das New York Magazine, Popular Mechanics oder Ebony, aber auch Popular Science und Bulletin of Atomic Science. Auch Men's Health ist dabei. Andere Titel sollen noch folgen. In Googles Buchsuche kann man die indexierten Zeitschriften nach verschiedenen Begriffen durchsuchen. Für die Magazine selbst gibt es allerdings kein Verzeichnis: Eine gezielte Suche nach einer bestimmten Zeitschrift ist deshalb nicht möglich. Die einzelnen Ausgaben stehen als vollständige farbige Scans zur Verfügung. Neben einem Inhaltsverzeichnis wird auch eine Liste mit Schlüsselbegriffen der jeweiligen Edition angezeigt. Eine Unterteilung nach Jahreszahlen gibt es ebenfalls."

- Abstract
- Designing systematic access to Internet resources is a major item an the agenda of researchers and practitioners in the field of information science, and is the focus of this study. A critical analysis of classification schemes used in major portals and Web classified directories exposes inconsistencies in the way they classify Internet resources. The inconsistencies indicate that the developers fall to differentiate the various classificatory models, and are unaware of their different rationales. The study establishes eight classificatory models for resources available to Internet users. Internet resources can be classified by subjects, objects, applications, users, locations, reference sources, media, and languages. The first five models are contentrelated; namely they characterize the content of the resource. The other three models are formst-related; namely they characterize the format of the resource or its technological infrastructure. The study identifies and formulates the eight classificatory models, analyzes their rationales, and discusses alternative ways to combine them in a faceted integrated classification scheme.

- Abstract
- Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln
