    Abstract
    Explains how 5 Internet search engines (AltaVista, HotBot, InfoSeek, Lycos, and Yahoo) handle field searching. Includes a chart which identifies where on a search engine's page a particular field is searched and the prefix syntax used, and gives examples. Details the individual fields that can be searched: data, title, URL, images, audiovideo and other page content, links and page depth

    Abstract
    NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    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
