The key research areas of biomedical engineering are identified and analyzed. It is demonstrated how biomedical engineering fits into the world map of science. An analysis of biomedical engineering core journals provides statistical data about citation patterns in this discipline.
High-impact medical journals are identified using data from the 1981 and 1982 Journal Citation Reports. The Journal Citation Reports are an annual supplement to the Science Citation Index. Journals publish different types of editorial matter, much of which does not report substantive research. A special algorithm is used to calculate the number of substantial or "meaty" items. In 1981 The Lancet and The New England Journal of Medicine ranked highest among 78 journals in citations received; 53,945 and 47,887, respectively. These journals also have the highest impact factor, the average number of citations received by items in a journal's 1980 and 1981 issues. The British Medical Journal was highest in 1981 immediacy index, the measure of how quickly a journal's 1981 items were cited in 1981.

In 1974 the Science Citation Index (SCI) covered about 401,000 articles and communications in 2,443 scientific and technical journals. They cited about 3.2 million different publications an average of 1.8 times each. In this article some results of an analysis of more than 5 million citations in the references of journal articles indexed for the SCI in 1974 are presented and an attempt is made to interpret of those results in the light of an earlier study of 1969 citations.

Many ongoing selective dissemination systems designers assume that the librarian can be omitted from active participation in execution of the master plan. ISI's four years of experience with ASCA(R) service have shown that librarians must be an integral part of the system and engage in an active dialogue between users and the machine. Specific examples of how librarians can best serve the information needs of scientists using SDI systems are examined. It is the basic contention of this paper that the librarian should serve as an intermediary between users and the numerous new information media. In this manner the librarian can filter and translate the requirements of individual scientists to conform with the inherent limitations of all machine systems while exploiting their capabilities to the fullest.
