THIS BOOK, like its predecessor, Woodrow Wilson and the Lost Peace, is to some extent a synthesis and largely an interpretation or reinterpretation of certain basic facts. It contains more significant new data than the earlier volume; hence the Bibliographical Notes are somewhat more fully documented. Footnotes are not included in the text, primarily because it should be reasonably clear to the specialist after examining these Notes where the material in question may be found.
Public opinion was even more vitally important in peace-ratifying than in peace-making, and for this reason more emphasis is placed upon it than in the preceding volume. The New York Times was followed throughout, and for specific periods use was made of the various other newspapers herein listed. The periodical press was most helpful, including the Independent, the Outlook, the New Republic, the New York Nation, the Review of Reviews, and particularly Harvey's Weekly, Current Opinion, and the Literary Digest.
Although the already-exploited House Papers at Yale University were of some value, the significant manuscript discoveries were made in the Ray Stannard Baker Collection, the Lansing Papers, the Hitchcock Papers, and particularly the Wilson Papers -- all in the Library of Congress.
In the bibliographies and notes that follow, the full citation is given the first time only; thereafter the shortened form. Where quoted material appears in italics, both in the notes and in the text, these have been inserted by the present writer, unless otherwise indicated.
