    Abstract
    Search Engine Watch is a WWW meta site giving organized, up-to-date information on WWW search engines. It is mostly free with a $25 charge for extra subscriber services. It has valuable links to a wide variety of other resources and charts comparing services. Despite its informality and idiosyncrasies of an individually sponsored service, it is an useful site

    Abstract
    Compares the features and performance of 6 Web search engines: AltaVista, Excite, HotBot, Infoseek, Lycos and Northern Light; 2 metasearch engines: Savvy Search and Inference Find; and the question answering system Ask Jeeves. Results of a standard set of 10 questions posed to each service show little overlap between search engines, so it is important to use more than one Web search engine if a comprehensive search is needed. Discusses technology trends and makes recommendations for Web searching. More and better information has become available on the Web in 1998 and each major search engine is developing a niche market and its own personality
