John F. Kennedy on Leadership: The Lessons and Legacy of a President by John A. Barnes.
Another book on John F. Kennedy? What is there left to be studied that hasn't been studied already? His leadership. Remarkably, given the spate of "leadership" books that have been published in the decade since Donald Phillips's Lincoln on Leadership created the genre, no one has attempted a book examining the leadership style of the modern American president who is probably most closely identified with the term.
