The lithium librarian. An international index.

Lithium salts are being widely used for treatment and prophylaxis of bipolar affective disorder (manic-depressive psychosis) and are under investigation in more than 30 other illnesses. The relevant literature has grown from 43 articles published between 1949 and 1964 to nearly 4,000 today. A computer-based lithium librarian program has been developed that provides an up-to-date registry of all lithium references, rapid search capability, constant availability, and easy transferability to identical computer systems located on three continents. References provided by the system are more complete, more rapidly available, and less costly than references obtained from other bibliographic services. This specific response to the rapidly expanding lithium literature provides a model for comprehensive aquisition and searching of other specialized subjects areas needed by clinicians and researchers.
