The hospital library: access to information for rural health professionals.

This article examines some recent literature about the low physician-population ratios in rural areas. In an attempt to discover those factors which seem to preclude successful health care delivery in rural areas, it discusses a definition of the city as the place where the maximum lines of communication converge. A new concept, the "invisible city," is proposed, and the health care community in the United States is seen as an example. The library of the rural hospital, then, is defined as the location of the rural health professional's primary entrance into his own invisible city by means of professional communication through the biomedical literature.
