The Alternative Press Center (APC), a non-profit collective, is devoted to "providing access to and increasing public awareness of the alternative press." The APC publishes the Alternative Press Index (API), a comprehensive quarterly subject index to more than 260 alternative periodicals in the social sciences and the humanities. The APC Website provides organizational information as well as information about the content and function of the API. The site also includes an online directory of periodicals in the API, listing subscription information, email addresses, and URLs. In addition, the APC compiles annotated links in a section entitled Alternative Viewpoints on the Internet. The compilation, comprised of over 330 sites, may be browsed by name or subject.
