The citation study technique, known as bibliometrics, was undertaken in this study to evaluate scholarly exchange among the core journals in the field of communication. The journals studied were "Central States Speech Journal,""Communication Research,""Journal of Broadcasting,""Journal of Communication,""Journalism Quarterly,""Public Opinion Quarterly,""Quarterly Journal of Speech,""Human Communication Research," and "Communication Monographs." From the number of articles published each year from 1975 through 1979, the following measures were constructed: the number of articles published, the number of citations made, the number of citations made per article, and the ratio of citations received to citations made. Results indicated that (1) most citations were to other core communication publications, (2) despite an apparent trend toward theoretical integration in some areas of communication research, there remained a rather distinct grouping of interests, and (3) the "Public Opinion Quarterly" was the only journal that did not reciprocate citations with other communication publications.
