New trends in medical libraries in hospitals.

External and internal forces affecting medical library services are examined. Public Law 89-239, the Heart, Cancer and Stroke Amendments of 1965, and Public Law 89-291, the Medical Library Assistance Act of 1965 which was extended by Public Law 91-212 have an impact on medical libraries. The Veterans Administration relationships with primary beneficiaries of these laws are explained. Internally, effort has been expended through automation, networking, and extension of resources by amalgamation of books and audiovisuals to evolve responsive concepts with emphasis on independence through interdependence. The Veterans Administration Library Service plans and accomplishments in these areas are reviewed.
