This directory is the second in an annual series of Internet guides for educators and librarians, and provides tips on access to, as well as addresses for, online resources that support the K-12 curriculum and supplement school library core collections. The listings in the catalog are limited to free and frequently updated resources; over 300 new annotated listings have been added to encompass electronic journals and newspapers, e-mail discussion groups, free-nets, and world wide web sites. Resources are grouped topically, with chapters on art, music and drama; foreign languages; language arts; math and computer science; science; social studies and geography; reference; and school library media applications. Other features include information about national, state, and regional networks, resources for the educator's professional development, and a discussion of the benefits of Internet access for disabled or culturally diverse students. A bibliography and index are also provided. (BEW)
