It depends on the author, and, quite possibly, their popularity. Probably the examples that come first to mind are many books by Orson Scott Card (including Ender's Game, Speaker for the Dead, and Treason), as well as Tolkien's novels. Stephen King did it with The Gunslinger and The Stand. And while I don't think Frank Herbert ever did it with novels published as such, he did often make changes between serialization and print versions.How many books does one generally see re-edited, with new chunks added years after they were initially published?
Hm, more than I expected then. I was generally thinking of books that were considered 'finished' and then went back and revised later on. I don't think I've read any of those (yeah shame on me
