Discusses the deficiencies of search engines and the importance of metadata and examines three models of metadata retrieval: distributed; distributed data with a centralized index; and centralized union catalog. Highlights include the Z39.50 protocol; the OAI (Open Archives Initiative) protocol; virtual union catalogs; and a pan-European model.…

Discusses subject gateway sites and commercial search engines for the Web and presents an explanation of Google's PageRank algorithm. The principle question addressed is the conditions under which a gateway site will increase the likelihood that a target page is found in search engines. (LRW)

Reports findings of a three-part research project that examined the information seeking behavior and success of 22 seventh-grade science students in using the Web. Discusses problems encountered, including inadequate knowledge of how to use the search engine and poor level of research skills; and considers implications for Web training and system…
