The papers consist of correspondence, research notes, memoranda, writings, speeches, newspaper clippings, and memorabilia of Edwin Borchard, professor of law at Yale University, specialist in international law, adviser to government and business, and controversial advocate of American neutrality in both world wars. The correspondence reflects both his political and legal interests. Most important among his correspondents is John Bassett Moore, with whom he exchanged over 2,000 letters between 1917 and 1947. Other political figures and organizations include the America First Committee, the American Civil Liberties Union, Charles Beard, William E. Borah, John H. Danaher, Hiram Johnson, James A. Shanley, and George Holden Tinkham. Extensive subject files in the papers relate to Borchard's work as a member of various international commissions as well as in United States law and politics. The files contain research notes, memoranda, minutes of meetings, and related correspondence. The section on his writings, which are preserved in both typescript draft and printed form, includes books, articles, speeches, pamphlets, book reviews, and a draft for an unpublished book on enemy property. Only a small part of the papers relate to Borchard's work as a professor of law at Yale University and there is no family correspondence.
