Reddit reviews All Music Guide to Electronica: The Definitive Guide to Electronic Music

This is going to date me, because I don't even know if this still exists, but around when I started getting seriously into the scene I picked up a copy of AMG's Guide to Electronica. It doesn't have a great poster, but there is a tremendous amount of info there.

You can probably get most of the info from their site, which is unfortunately a travesty, but at least it'd be up to date.
