The most important part of the Thomas Hartley Crawford Papers relate to Crawford's work on a presidential commission investigating land fraud in connection with the 1832 treaty with the Creek Indians. There are also legal opinions, reports, financial records and correspondence with members of Congress which reflect his work as Commissioner of Indian Affairs, 1836-1845, and as a judge in Washington, D.C., 1845-1861. Among his correspondents are Dixon H. Lewis, C. C. Clay, William Mitchell and J. C. Ten Eyck.
