The Bennett papers consist mainly of correspondence, writings, addresses and records from organizations in which Bennett was involved. Correspondence ranges from UTS-related matters to individual correspondence, much of it international and on themes of interest to Bennett, such as pacifism and communism, as well as important correspondence related to four U.S. presidential elections. A significant collection of lectures, sermons and addresses covers the full range of Bennett's ethical, political and human rights interests. His writings are represented by articles, reviews and contributions to volumes with accompanying correspondence.
