Eugene O'Neill's autobiographical play Long Day's Journey into Night is regarded as his finest work. First published by Yale University Press in 1956, it won the Pulitzer Prize in 1957 and has since sold more than one million copies. This edition, which includes a new foreword by Harold Bloom, coincides with a new production of the play starring Brian Dennehy, which opens in Chicago in January 2002 and in New York in April.
