Pamphlets compiled by various authors and institutions and published by the foundation to educate people on the waste and destructiveness of war and to promote international justice and the brotherhood of man. Founded in Boston in 1910 by Edwin Ginn, the foundation concerned itself with many of the events leading up to and including World War I and its aftermath, as well as the promotion and operation of the League of Nations. In October 1917, when this collection begins, the foundation changed the title of its pamphlet series to League of Nations. It discontinued this title in 1923 with volume 6, no. 3, and returned to the World Peace Foundation series title, and described itself as the "American agent for the official publications of the League of Nations."
