RESEARCH NEWSLETTERS IN THE BIOLOGICAL SCIENCES—A NEGLECTED LITERATURE SERVICE Available to Purchase

A number of informal biological newsletters have a limited circulation. In addition to social news some of these contain information about research in progress, research material, and select bibliographies—these are called research newsletters and an analysis is made of the contents and scope of twenty‐two of them. The bibliographies are of several types and that compiled from the publications of the recipient's newsletter is discussed and its cover compared with that of Biological Abstracts. Suggestions to improve the usefulness of the research newsletters are made.
