Composed of miscellanies from both the era of the Forum and the time of the Ethical Culture Club. Materials from the latter era consist of the record of meetings from the years 1908-1910. Material for the latter years includes the minutes of meetings, a copy of the constitution, some miscellaneous materials and a history of the club written by William Powers.
This collection is composed mainly of Powers' notes and materials he wrote about his history of the college. For the most part, these are draft materials. Also included are some correspondence and some totally unrelated material. This material includes notes about the foundation of the Brookings Public Library, and notes on the World Disarmament Committee, including a petition against conscription signed by many university faculty.
