Earlier collections included the extra pages that contributed to the story, but skipped those that served as recaps. But this isn't a "director's cut" edition. I believe it's intended as a reproduction of the original books. In fact, it's so faithful that there are a few interesting easter eggs in there for people who never read the comics, such as idiosyncratic lettering that lends it a more underground feel. It also lacks the subtle edits made to dialogue and narration for other collections.
