The official American documents that bear upon the Paris Peace Conference of 1919 are of enor- mous volume and are located in several archives. Thousands have been printed in one or both of two basic collections: (1) Papers Relating to the For- eign Relations of the United States, 1918 and 1919 series, Paris Peace Conference series and Lansing Papers, vol. 2 (published by the State Department, Washington, D.C.); and (2) My Diary, by David Hunter Miller, consisting of twenty-one volumes (repr. Peter Smith, Gloucester, Mass.). Miller, in editing his twenty-one volumes, drew upon his papers in the Library of Congress.
I have searched the files from which the docu- ments in the above compilations were taken and have made use of some papers not previously printed. Moreover, I have drawn upon relevant documents of the Treasury Department, both those in the National Archives and those in the "Peace Commission" file in the Bureau of Accounts. In many cases it has been possible to compare the written record with oral testimony from interviews granted to me by men who wrote the documents. Witnesses who have contributed information in an interview or by correspondence, other than those whose papers are listed below, are Philip Noel- Baker, Sir James R. M. Butler, François Charles- Roux, Robert H. George, Andrew Géraud ("Per- tinax"), Ulysses S. Grant III, Lord Hankey, Mrs. J. Borden Harriman, Wunsz King, Arthur Krock, David Lawrence, Eleanor Wilson McAdoo, Fran- cis C. MacDonald, René Massigli, George Ber- nard Noble, Bliss Perry, William Phillips, André Portier, René de St. Quentin, Sir Arthur Salter, Francis B. Sayre, Herbert Bayard Swope, Arnold Toynbee, and Mona House Tucker.
The following collections have been used; and in many cases I have talked with those who cre- ated them.
