This is next on my reading list as I am almost done Morrison's Batman run. My question is, are these crossovers and tie ins that I will need to get from other series for the full read?
I don't want to be reading an arc only to find out Part "x" takes place in another series. I basically want to have everything together in my hand so I don't have to go searching later on.
I do know there are some JLA/JSA crossovers as well.
