I got the Morrison Batman omnibus today and one thing I was very pleased to see is that the credits, which were removed in other reprints (at least the ones I've seen), have been restored here - not exactly as they first appeared, but in a shortened version with only the writer/artist/colorist/letterer credits, which I recall DC also used for the Batman Incorporated collections. DC doesn't usually include credits if it already has a version out there without credits, so I hope this becomes a habit.
I'm a believer that reprints should always have the credits where they originally appeared on the page (sometimes DC would eliminate not only the credits but the title and the design of the pages would make no sense), but with Morrison you can tell that he and his collaborators put a lot of thought into where the credits should go and how they should be designed, so I really hope the upcoming Morrison reprints continue this.
I haven't had a chance to find out if there are any mistakes in the book, but I wanted to give, er, credit where due.
