    Abstract
    Kompetenter Überblick über die verschiedenen Werkzeuge, die für die Informationssuche im Netz zur Verfügung stehen. Er beschränkt sich nicht nur auf die übliche Beschreibung von Yahoo, Altavista & Co., sondern geht auf alle wichtigen Informationsquellen im Internet und den Onlinediensten ein. So beschäftigt sich der Autor auch mit der Recherche im Usenet oder in Mailinglisten und erläutert die unterschiedlichen Newsquellen in Compuserve, AOL und T-Online

    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
