THE CONTEMPORARY MEDICAL SOCIETY LIBRARY.

Four hundred sixty-eight medical societies in the United States were surveyed to determine those which sponsor libraries. Seventy-eight libraries were identified, of which eighteen are "marginal" and nine are jointly supported by a medical school and a society, leaving fifty-one relatively "substantial" libraries whose major support is through society membership. Characteristics measured include size of collection, types of media, staff, budget, services, and sources of support. Questions are raised concerning the role of the medical library as one institution which participates in the continuing education of the physician.
