So I just discovered that inter library loan is a godsend for comics and I'm using it to read some DC stuff. I've mainly been reading Marvel because I have a MU subscription and I can't really afford to buy enough to catch up to New 52. Anyway, if I want to read current Batman, do I need to read every series or can I just stick to the main Batman book? There's like a million different Batman series. Will I be lost if I don't read them concurrently with one another, or do they pretty much remain self contained?
