World‐Wide Web searching tools: an evaluation Available to Purchase

In this article, four search engines and two subject collections with a search facility are compared in terms of their content, interface, search features, output and performance. For comprehensive searches of Web material, no single tool was found to be satisfactorily effective, and doubts remain as to whether such tools can yet be incorporated in the mainstream of online searching.
