The Roger Nash Baldwin Papers document the life and career of Roger Baldwin (1884-1981), a prominent and active American civil libertarian for almost all of his prodigiously long life. Baldwin is remembered first and foremost as a founder of the American Civil Liberties Union. Many of the papers in this collection document his involvement with the conscientious objection movement that served as the forerunner to the ACLU and with the Union itself. He served as both its executive director from its foundation in 1920 to his retirement in 1950 and as an advisor from that date until his death in 1981. However, Baldwin cast his net much wider than just the ACLU. During the 1920s and 1930s, he was involved with various left-wing political organizations, including the Industrial Workers of the World. Following the end of World War II, he served as an advisor to the U.S. Army and the United Nations in Germany, Austria, Japan, and Korea, guiding the establishment of democracy in those countries, and he was for many years chair of the International League for the Rights of Man. He spoke and wrote widely, most often on issues of civil liberties and human rights, and also taught periodically throughout his life. The papers, which include correspondence, memos, writings, notes, and photographs, document all aspects of his public life, as well as some portion of his personal life.

The Records of the Association on American Indian Affairs document the corporate life of an influential and resilient player in the history of twentieth-century Native American advocacy. From its formation by non-Indians in New York in 1922 to its re-establishment in South Dakota in 1995 under a wholly Indian administration, the AAIA has defended the rights and promoted the welfare of Native Americans and, in this process, has shaped the views of their fellow citizens. The AAIA has waged innumerable battles over the years, touching on the material and spiritual well-being of Indians in every state of the Union: from the right of Native Americans to control their resources to their right to worship freely; from their right to federal trusteeship to their right to self-determination. The evolving nature of this struggle, in terms of conception and execution; the environment in which it was waged, both within and without the AAIA; the parade of men and women who figured in it; and the relationships among them can all be found in the abundant and insightful records which constitute these Records. The correspondence, minutes, reports, articles, clippings, and other documents in the collection, augmented by photographic and audiovisual material, represent a window not only on the AAIA but on the entities and personalities with which it interacted. While its vision has co-existed with others, and while it has been far from alone in its contribution to Indian life, no consideration of twentieth-century Native American affairs can disregard its arduous and, for the most part, fruitful work.
