What encompasses Morrison's DC saga? How should it be approached?
Great question! Let’s put together a reading list.
This is going to be a lot, and even seem like it’s everything he’s done for DC, but it’s actually not. I’m only going to include the things through which you can trace particular story threads. So, for example, even though his work on Doom Patrol with Richard Case is ostensibly about DC superheroes, it does not cross over in any way with his work on Superman or Batman or whatever.
I think probably the best way to work through this stuff is chronologically by publication, more or less, so I’m going to list it that way. Here we go!
JLA Classified #1-3 (this used to be collected in the JLA vol 4 HC, but is not in the TPB, I guess? Doesn’t seem to be collected anywhere else. edit: Oh yeah, there’s this. It’s out of print, but can be obtained used for low prices.)
(optional, as not by Morrison, but recommended: The Black Casebook)
Return of Bruce Wayne (what you should really do is read the last volume up through issue 15, then read RoBW, then go back and finish the last volume. I think I’ve got that straight.)
Batman Incorporated vol 1 (no, the OTHER vol 1)
(or instead of the last two volumes, get the Absolute Batman Inc)
Aaaaaaand I think that’s it? You can also read Gothic if you want all of Morrison’s Batman stuff, but it doesn’t really tie in to everything else except maybe in terms of themes and motifs.
And like, for a fuller, rounder understanding of some things, you should probably also read non-Morrison stories that influenced his work, like Jack Kirby’s Fourth World, Len Wein’s run on Justice League, and Dark Knight, Dark City.
Happy reading! Sorry if your wallet takes a hit.
