    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

    Abstract
    Reports results of a study, undertaken at the J. Otto Lottes Health Sciences Library, Missouri University at Columbia, to derive a set of evaluation criteria to assist librarians in determining the positive and negative aspects of alternative Web sites available for searching MEDLINE via the WWW. A set of searches were used systematically to compare MEDLINE Web sites, including: Avicenna; America Online; HealthGate; PubMed; Medscape; and Physicians' Online. Focuses on the principle features of the search engines used in the sites: default fields and operators; MeSH; subheadings; stopwords protected in MeSH; truncation and stemming. Describes the group processes used to arrive at the evaluation criteria and some general conclusions which will help librarians in directing their users to a particular MEDLINE site

    Abstract
    This research continues to explore the user's evaluation of Web search engines using a methodology proposed by Su (1997) and tested in a pilot study (Su, Chen, & Dong, 1998). It seeks to generate useful insight for system design and improvement, and for engine choice. The researchers were interested in how undergraduate students used four selected engines to retrieve information for their studies or personal interests and how they evaluated the interaction and search results retrieved by the four engines. Measures used were based on five evaluation criteria: relevance, efficiency, utility, user satisfaction, and connectivity. Thirty-six undergraduate juniors and seniors were recruited from the disciplines of sciences, social sciences and humanities. Each searched his/her own topic on all four engines in an assigned order and each made relevance judgements of retrieved items in relation to his/her information need or problem. The study found some significant differences among the four engines but none dominated in every aspect of the multidimensional evaluation. Alta Vista had the highest number of relevant and partially relevant documents, the best relative recall and the highest precision ratio based on PR1, Alter Vista had significantly better scores for these three measures than for Lycos. Infoseek had the highest satisfaction rating for response time. Both Infoseek and Excite had significantly higher satisfaction ratings for response time than Lycos. Excite had the best score for output display. Excite and Alta Vista had significantly better scores for output display than Lycos. Excite had the best rating for time saving while Alta Vista achieved the best score for value of search results as a whole and for overall performance. Alta Vista and Excite had significantly better ratings for these three measures than Lycos. Lycos achieved the best relevance ranking performance. Further work will provide more complete picture for engine comparison and choice by taking into account participant characteristics and identify factors contributing to the user's satisfaction to gain better insight for system design and improvement
