Need some help locating a comic

[Capeless Hero]

Hey guys Im not a usual on this board but I know you guys know your stuff and are always willing to help. Do you all know if there is a graphic novel containing "The Killing Joke" or was it just one amazing comic with a bunch of single issue stories?

 

[Mister J]

DC Universe: The Stories of Alan Moore

Should still be available in a number of locations. The original solo edition of TKJ is out of print, but the book I listed contains that, as well as some other good stories.

And it is an amazing comic.
