The quality of medical care is dependent on effective and expeditious information services for physicians and other health workers. Small hospitals have been at a particular disadvantage in this respect, mainly because unit costs of library services have been quite high when delivered on a small scale with traditional resources and methods. The importance of this problem is suggested by the fact that more than half of the US hospitals have less than 100 beds, and that library services have been primitive or nonexistent in most of these institutions. Certain recent developments will permit most of these smaller hospitals to provide creditable information services at modest cost.
