Although his work as a historian was secondary to his religious calling, he served as a member of the governing and editorial boards of the Utah State Historical Society from 1943 to 1952. Dwyer periodically acted as editor to the Utah Historical Quarterly, and produced two noted volumes. In 1943, he edited work on the diary of Albert Tracy, a soldier in Albert Sidney Johnston's troops during the Utah War and in 1946 he edited a volume on Mormon pioneer Lorenzo Dow Young which contained a biography of Young by James Amasa Little, an edited diary of Lorenzo Dow Young and additional information on the pioneer's extensive family.
