I appreciate all the linking you're doing all over the place but I have one request. Please don't link the disambigs in the articles' histories. Like, for example, on the Pamela Isley (Burtonverse) page you linked Batman, Robin, Bane, etc. It's nice to see blue links scattered, but, if somebody wanted to see the Bruce Wayne (Burtonverse) page, they might accidentally click on the Out-of-Universe disambig link instead. Y'know?
If the original hardcover included the LotDCU one-shot, we should probably put that on the page. However, since none of the numerous sources I've consulted say anything about it, it would probably be best if you could get firsthand confirmation by finding your old copy. Perhaps you could even scan the copyright page: it should break down exactly how its contents were originally published.
