Like with continuity and stuff? For example, I'm reading Batman Knightfall Volume One right now. It's pretty bad ass and I understand there are three volumes, but how does this relate to all the other Batman comics that have been made since the 1940s? When you read Harry Potter, you start with the Sorcerer's (or Philosopher's) Stone and read it all the way through until the Deathly Hallows. How does this work for comics that span 50 years? Thanks for the feedback.
