What is actually the "definitive" guide to Batman?

Im looking for a guide that spans from Detective #27 to today covering comics, movies, TV, etc and everything Ive found so far either skims over with just highlights or they focus on one medium. I would love some suggestions.

@pineboxdaddy: I haven't read either of these myself, but I've read good things about Batman: The World of the Dark Knight and The Essential Batman Encyclopedia.

Welcome to Comic Vine, by the way. :)

These sound good. There's also Batman A Visual History, @bezza and @lamdaddy20 can tell you more about it.

thank you very much @battle_forum_junkie and @rustyroy ! You both were very helpful and thanks for the warm welcome!
