Editors and scholars are still fiddling with some of Joyce's and Faulkner's works. Was a word or phrase actually what was written by the author, or has an editor or printer made a mistake? Trying to re-interpret the original manuscripts and the author's revisions in order to come out with a more correct edition has led to multiple editions of Finnegans Wake, each striving to be the most accurate (and several "readers guides" as well).
