"A comparative study of the inclusion or non-inclusion of selected abstracts and the priority of their publication, found in twelve areas of physiology chosen from Biological Abstracts and British Abstracts for the year 1946, is believed to be effectively useful (1) in giving librarians and specialists in this field an indication of whether or not both abstracting services are needed, and, if both are not, which is to be preferred in various types of research or university libraries; (2) in suggesting to the publishers some of the strengths and weaknesses of the general features of each of these two journals; and (3) in determining from the standpoint of the user, the relative merits of their systems of classifying and indexing science articles.
