Samuel R. Delany recommended this book to me on Facebook, as I was finishing Ulysses itself. This is the story of the text of Ulysses, after it was published, and through separate editions, and especially the unfortunately Gabler edition published in the late 80s. The story is told very well, and it is a scandal that a new edition was published with very little feedback from the literary world. A superb book, and if you are interested at all in the topic I highly recommend it.
