摘要：IN THE fall of 1978 a questionnaire was mailed to 120 major biomedical libraries, primarily those serving the accredited medical schools listed in the AAMC Directory of American Medical Education, 1977-78. A total of eighty-eight useful responses was received by the requested date, for a 73% return rate. The survey was intended to elicit information about the current use of Biological Abstracts, Chemical Abstracts, Psychological Abstracts, Science Citation Index®, and Social Sciences Citation IndexTM (SSCIm). The impetus behind the survey was a hypothesis that continued subscriptions to some of these were becoming counterproductive, because (1) the number of physical bound volumes per year was increasing almost geometrically and (2) access to the information contained in some of these could be accomplished as easily and less expensively through the equivalent on-line bases.
