Concerns the Department of Interior files largely documenting the drafting and implementation of the Indian Reorganization Act of 1934 (IRA, known originally as the Wheeler-Howard Act), a 1939-1940 survey of Indian Law that resulted in the publication of The Handbook of Federal Indian Law, and routine legal work concerning the department's Indian policies. The files consist of internal memoranda, correspondence, drafts of reports and legal opinions, printed bills and drafts, and printed material by government agencies and private institutions.
