Abstract
A survey was conducted by a simple mathematical method using the List of Current Periodicals Acquired by the Japanese Medical, Dental and Pharmaceutical Libraries, 1977ed. to 1982ed. (six years), to identify the following: 1) the 760 titles mostly acquired by the JMLA member libraries, 2) the 113 additional titles newly acquired by the twenty libraries over the six years in question, and 3) the 59 titles which had decreased or not changed from the total of acquisitions during the same period despite an increase in the member libraries. The relevant titles were also analyzed according to their countries of publication, and the subjects of their contents.
