    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

    Abstract
    Reprots the results of a study which sought indications of the effectiveness of searching for information on the WWW versus the traditional online vendors, for comparisons of how it took to search, and for comments on the relative value of the results retrieved. Professional searchers were invited to search for answers to the same questions on both the WWW and on either DIALOG or Dow Jones Interactive. Overall DIALOG / Dow Jones Interactive retrieved more relevant documents and total searching time was more than double for finding information on the Web. Summarizes the comments from searchers on: searching assumptions of professional searchers; the subjects and types of searches for which DIALOG and Dow Jones Interactive showed superiority; areas where the Web has advantages over traditional online services; and uses for which both traditional online vendors and the Web can supplement each other. Lists nine searching principles for maximizing success when using Web search engines
