Abstract

To use the electronic resources of the Internet effectively, reference librarians must learn to use the various search engines to their best advantage. Describes the following Web sites which provide help for librarians in improving their Internet searching skills: the Bergen County Cooperative Library System which has links to some well-known directories and search engines; the Spider's Apprentice, which provides ratings and in-depth analysis of search engines, a FAQ document useful to the beginning searcher, and an online discussion forum; ZDNet's WebSearchUser which has feature articles, reviews and tutorials; and Search Engine Watch which reports new developments in search engines. URLs for these and other resources are given
