Wait this is not a thread complaining or questioning the present state of DC comics continuity.

It's just that now that everything matters and DC can reference other stories (regardless of reboots and timeline changes) some people are probably going to be confused. So let's be helpful fans to one another, by letting people know key stories that either have been referenced as of late or really inform the character(s) and can help people start reading books they want to get into.

I'll get started with some characters in separate posts following this original post that are specific to the character. However, don't be afraid to just jump in with your own additions to characters and lists.
