Psychiatric Services offers a monthly listing of mental-health-related Web sites and other sites of interest. The list changes monthly as new sites are identified and existing sites add new features. We'd like maintaining the list to be an interactive process, so tell us about your favorite sites or what you'd like to be able to find on the Web. You can reach us by e-mail at psjournal@psych.org.

Bureau of Primary Health Care—www.bphc.hrsa.dhhs.gov

The mission of the Bureau of Primary Health Care (BPHC) is to increase access to comprehensive primary and preventive health care and to improve the health status of underserved and vulnerable populations. BPHC is one of four bureaus of the Health Resources and Services Administration, an agency in the Department of Health and Human Services. The Web site provides descriptions of more than two dozen BPHC programs, including safety-net activities such as the Health Care for the Homeless Program, technical assistance programs for states, and scholarship programs to place health care professionals in shortage areas. The site also offers information on a major new initiative of the bureau, the Center for Communities in Action, whose goal is to help communities build partnerships with hospitals and health maintenance organizations to ensure access to health care for all community residents. An extensive list of links takes visitors to primary care sites on topics such as AIDS, cultural competence in health care provision, and women's health.
