Feeling that none of the existing editions of Ulysses adequately represented the text of the novel, Philip Gaskell and Clive Hart looked again at the evidence of Joyce’s manuscripts, typescripts, and proofs, and have produced lists of suggested alterations for the three most important editions of the book: the first edition of 1922, the standard American edition of 1961, and the so-called ‘corrected’ edition of 1984. They believe that a copy of any of these editions, marked up with the alterations they propose, will result in a text closer to what Joyce intended in 1922 than any that has yet been achieved. What is offered here, in fact, is not a new edition of Ulysses, but a kit for repairing the major faults of existing editions.
