Whew! That wimpy trade paperback DC put looks pretty lame right now, doesn’t it? The rest of the DC1M issues are completely standalone and could be (if so desired) bound separately in any order (actually, I take that back: the Legion & Legionnaires issues might tie together, but someone else will have to confirm that):

Azrael
Chase
The Creeper
Green Arrow
Hitman
Legion of Super-Heroes
Legionnaires
Lobo
Supergirl
Young Heroes in Love
Young Justice

There is also a DC One Million 80-Page Giant that you do a few things with:

-Take the Grant Morrison pages out and add them to the end of the main book, or if you don’t mind a thicker book, use the whole thing.
-If you bind the standalone issues in their own volume, put it at the beginning.

Chris Roberson revisited the 1M timeline in Superman/Batman #79-80, and would be a great addition as well.

I just bound the core story, but there are definitely options for those who want everything.
