• As for the multiple editions, in the case of a truly great writer - Shakespeare, Emily Dickinson, Proust, someone with a canon - there is often a "variorum" edition of the work that presents its variants. I think publishing most other writing that way would be impossible, economically, for publishers, and very ill-advised for authors.
