    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
