>>85438047Just read the 2009 print of The History of the DC Universe, it's a mix of both the original 80s History of the DC Universe that focuses on the Post-CoIE continuity, written by Mark Wolfman and Perez, and a new resume of the everything else that happend up to the begining of Final Crisis (including smaller Events like No Man's Land and Our Worlds at War).
I have to admit I love this fucking book, and it's the reason I fell in love with DC. Reading the small one panel introductions to all the of the 80s DC series/characters really spaked my imagination, and I ended up making up several stories involving characters like Amethyst, The Haunted Tank, Atomic Knight, Arion, Space Cabbie and Creatue Commandos years before I ever actually read anything that featured them (I got some pretty off ideas about what some of them were about, specially Atomic Knight). It will also make you undestand why some many people were mad a New-52, all that nice lore, gone.
As per Post-New-52, the jury is still tecnically out on that, since Superman and Lois Lane of pre-New-52 Earth exist, even though New-52 and Pre-New-52 are apparently the same universe with "5 years missing".
