The Society of Friends series is composed of records and materials for informational or political events from the Society of Friends ranging from 1968 to 2024. Many of the materials regard events made to advocate for anti-war and in opposition to violent conflict. Many of the materials are in the form of Union-Bulletin publications, event flyers, informational guides, meeting correspondence and letters, articles, pamphlets, poems, songs, and newsletters. Much of the correspondence and informational materials regard the Committee on Nonviolent Resolution. Many articles are from the Union-Bulletin which have been quoted in Daniel Clark’s blog “The Unitive Self” where he writes about his personal philosophy and thoughts on spirituality.
