摘要:THE CONCEPT of the clinical medical librarian (CML) was developed by Dr. Gertrude Lamb, and its implementation was announced to the profession by Algermissen in 1974 [1]. Since then, clinical medical librarianship has been enthusiastically adopted in a variety of settings, but usually within a physician or medical student population [2-4]. CML has been successfully introduced into an entire nursing service of 500 to 600 R.N.s in the 619-bed Thomas Jefferson University Hospital in Philadelphia, Pennsylvania. The evolutionary process of introducing one librarian to an entire nursing service began in the early fall of 1978 when the librarian was challenged by the director of nursing service to help meet the information and continuing educational needs of her staff.
