Lister Hill Center is concerned with developing a computerized information system, with a data base consisting of an expanded Abridged Index Medicus, using part of a large computer system, and connecting this system to the TWX network. With this in view, a study was made of the demands on such a network, and a study of the SUNY network showed that on-line access more than doubled the use of the data base.Other alternatives to the TWX system are described. 相似文献

The development of education for medical librarians 总被引:1,自引:0,他引:1

Formal education for medical library specialization was initiated only thirty-two years ago despite the fact that medical libraries received special treatment for many years before that time. The philosophy of specialized education was developed as early as 1925, and this theory was finally put into practice beginning with the medical reference and bibliography course given at Columbia in 1939. In the late 1940s the requisites for medical librarians were formalized into a certification code by the Medical Library Association, and since that time specialized education for medical librarians has grown stronger using this code as a guideline. This education consists basically of two types-formal library school courses and internship programs which offer a working-while-learning situation. Now that the established programs have a few years of history, there is a need for evaluation and restatement of goals and methods. 相似文献
