Okay, I knew there was something rotten with this bibliography. As "future" offerings it lists Apocrypha 2 (done), Empire in Chaos (done, I think), Realms of Sorcery (done), and Dwarfs (done: Stone and Steel). My question then is: Were sourcebooks ever done for Skaven and/or Elves as advertised as "future" installments?
This is not the be all and end all bibliography I was looking for. It can't be with several works listed as being "in the works" when they were actually published years ago. I'm still looking for a complete and up-to-date bibliography.
