This collection of all O'Neill's published plays, including many which have been out of print for years, marks the centenary of his birth. 45 plays are included from his early sea-plays, his varied experimental period to the dramas of his maturity. O'Neill was awarded the Nobel Prize for Literature and four Pulitzer prizes including a posthumous award for "Long Day's Journey into Night". He is thought by some to have revolutionized the American theatre. John Lahr's introduction examines O'Neill from a psychological perspective and includes some discussion of his early childhood.
