The National Library of Medicine and the American medical information system: the physician's perspective.

During the past 150 years an excellent health sciences information system has been developed in the United States. Led by the National Library of Medicine (NLM), the system grew along traditional lines until after World War II, when medical researchers, educators, and practitioners produced an enormous amount of new information. To cope with this growth, the power of computers joined traditional librarianship and MEDLARS was born. In 1965 Congress passed the Medical Library Assistance Act, which enabled NLM to lead the nation's and the world's health sciences professionals into the Information Age. Much as been accomplished by NLM, yet much remains to be done to make health information available cheaply, easily, and quickly to all who need it.
