This book includes an introductory essay outlining main themes and problems of the era, a chronology of main events, and over 1,000 separate cross-referenced dictionary entries exploring all aspects of American Diplomacy. Additionally, appendixes providing lists of presidents; secretaries of state, war, and navy; all American diplomatic ministers and ambassadors, and most U.S. consuls are included. A photographic section with images of significant individuals and locations and a massive bibliography that is essential due to the neglect of literature on the epoch until recent decades conclude this work.
