This impressive research guide 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.
