Although Ambrose discusses Nixon's post-presidential roles as author and elder statesman, this final volume of his three-part biography ( Nixon: The Education of a Politican, 1913-1962 , LJ 5/1/87; one of LJ 's ``Best Books of 1987''; and Nixon: The Triumph of a Politician , LJ 11/1/89) is largely the story of Watergate. Unlike Tom Wicker's One of Us: Richard Nixon and the American Dream ( LJ 2/1/91), which credits Nixon as a domestic success, Ambrose concludes that because of Watergate, Nixon's well-intended national and international programs were not ``accomplishments but might have beens.'' The ultimate and, to Ambrose, tragic legacy of the president who wanted to be admired but not liked was the destruction of the moderate wing of the Republican party. Complemented by Roger Morris's Richard Milhous Nixon: The Rise of an American Politician and Herbert Parmet's Richard Nixon and His America (both reviewed LJ 12/89), Ambrose's three-volume biography is an indispensable acquisition for academic collections and is highly recommended for most public libraries as well.
