Summary

Summary

In this completely revised and expanded version of his award-winning book, the "extreme searcher," Randolph (Ran) Hock, digs even deeper, covering all the most popular Web search tools, plus a half-dozen of the newest and most exciting search engines to come down the pike. This is a practical, user-friendly guide supported by a regularly updated Web site.

Library Journal Review

With nary a hint of condescension, this solid video overview of the Internet discusses a fairly broad range of issues, making two important points: 1) the net is comparable to the biggest library ever owing to the linking of millions of servers full of information, and 2) no one actually designed the Internet, it just kind of happened an idea that might not come across clearly in a book. Other topics include standard terms, domain names, online auctions, and e-mail. Teachers could use this as a lead-in to a discussion or as a basic introduction for young or new users; recommended.

Choice Review

Professional researcher? Student? Businessperson? Whatever your Internet search needs, the second edition of Hock's book (1st ed., CH, Dec'99) is essential reading. Hock provides insight into how search engines can be used to gather specific information. He gives a very interesting history of search engines, then discusses common searching options (e.g., Boolean logic, nesting capabilities, truncation, phrase and proximity searching) with a detailed table showing field searching using different search engines. The book is full of helpful screen images, a thumbs-up or thumbs-down rating of various aspects of each search engine, and a summary of each chapter. The book's chapters describe eight of the most popular search engines, giving an overview, discussing what happens behind the scenes, and describing search features, result pages, special options, and more. Metasearch tools are described and discussed. The Extreme Searchers Web Page is dedicated to what's new and what has changed in the Web search engine world. Recommended for students, librarians, and professional researchers. V. L. Thompson University of South Carolina--Spartanburg
