This, the first volume in the new Greenwood Press series Reseach Guides in Military Studies, focuses on the United States Army during one of the most significant periods of its development. The years between the Spanish-American War and the onset of World War II saw the army mature into one with the institutional skills, technological knowledge, and trained commanders capable of engaging in a massive global effort. Following a detailed overview of the tremendous change that occured during this 40-year span, Fletcher presents two major sections of annotated bibliography, covering 1900-1917 and 1919-1941, respectively. Over 900 works are cited, including books, articles, dissertations, and government documents. Most have been published within the last 20 years. As the first research guide published covering this critical period in U.S. Army history, The Peacetime Army will be of significant benefit to military historians and students of military affairs.
