Question about Chris Ware's books

[Ivan In Da Crypt]

Im new to Chris Ware but really digging the stuff ive read so far... and so far the books of his ive got are the ones by Jonathan Cape (Random House)... The big red Acme Novelty Library, Quimby the Mouse and the Jimmy Corrigan collection.

However i wanted to know what the numbered issues of Acme Novelty Library from Fantagraphics are... do they contain the same stuff as the ones ive got up there?
and also, whats is the Acme Novelty Datebook?

any help would be appreciated

Acme is set up like Eightball,
it's Ware's on-going, most of everything else is selections reprinted from Acme
