A handful of books have won both the Pulitzer Prize and the National Book Award -- the two heavyweights of American literature.
These double-dippers are:
The Shipping News by E. Annie Proulx;
The Color Purple by Alice Walker;
Rabbit is Rich by John Updike;
The Fixer by Bernard Malamud;
The Collected Stories of Katherine Anne Porter; and
A Fable by William Faulkner.
