This is the sixth report of the fundamental investigations for the planning of the public library system to community area. The paper describes how to settle the adequate number of books for each branch library through the statistical analysis on the 212 branch libraries in U.S.A., 73 library systems in Great Britain, and 21 new branch libraries in Japan. In this analysis we found that the number of book circulation per capita of a branch library chiefly depended on the number of new addition per capita of the library. We present a figure showing these relationships, by which we can find the adequate number of new books and total volumes per capita, if we set up a goal for the number of circulation.
