When Ulysses was first published was first published Jmes Joyce wrote 'I am extremely irritated by all the printer's errors'. Are these to be perpetuated in future editions? I hope not'. Joyce's hope was not fulfilled until 1984 when this critical edition of the work appeared, the fruit of seven years textual research by a team of scholars led by Professor Gabler of the University of Munich. They had returned to the original manuscripts, drafts and proofs in order to reconstruct as closely as possible the creative process by which Joyce wrote Ulysses. Corrections to thousands of 'accidentals' of punctuation, spelling and emphasis illuminate previously obscure passages and throw the theme of the most significant novel of the twentieth century into sharp relief.
