The papers contain correspondence, sermons, other writings, and memorabilia, concerning both Owen's personal life and his work as an Episcopal priest. The bulk of the papers is composed of sermons delivered from Owen's pulpit in Holy Trinity Church, New York City. Much of the correspondence is made up of letters from World War I and World War II servicemen from Owen's churches, letters from fellow Episcopal clergy, or correspondence concerning Owen's coin collection. The papers also include Owen's inspirational writings and drafts for his memoirs.
