Judge Zobel recommends Irving Brant’s The Bill of Rights (Mentor edition, 1965); Carl Van Doren’s The Great Rehearsal (Viking, 1948) for general background on the Constitutional Convention; and for those who want to go back to the sources, The Debates in the Federal Convention of 1787 , edited by G. Hunt and J. Scott (Greenwood Press, 1970), which are the actual notes that James Madison kept during the proceedings. Zobel also recommends The Modern Library’s edition of the Federalist Papers, called simply The Federalist (1937).
