Editions of Ulysses

"...in the late 1970s a German critic and scholar named Hans Walter Gabler began the task of preparing a 'corrected text'. This was finally published in 1984, and greeted with, first, acclaim, then doubts, and finally outrage. From a deep split in English and German textual theory, the status of the all-important 'copy-text' (either the 1922 edition or Joyce's chaotic and imperfect manuscript) became the subject of a fierce scholarly debate between Gabler and his nemesis, John Kidd. The climax of this crisis occurred in June 1988 with Kidd's article in the New York Review of Books, entitled 'The Scandal of Ulysses'.

"Since then, the row has gradually subsided, with a loose consensus forming in support of Gabler's 'synoptic' text, while nevertheless acknowledging that it, too, contains some rank inconsistencies. Today, the first 1922 edition, a text of huge historical consequence, stands as the shortest route to the author's intentions, despite numerous Joycean 'misses in print'."
