An individual who searches for information for clients. Information brokers use various resources including the Internet, online services that specialize in databases, public libraries, books and CD-ROMs. They also make plain old fashioned telephone calls. The word "broker" is a misnomer. Information retrieval consultant would be more accurate. Sue Rugge and Alfred Glossbrenner wrote an excellent book on the subject, "The Information Broker's Handbook," published by McGraw-Hill (ISBN 0-07-057870-2). See Web search engines and online service.
