Here's a tip of the hat to the splendid site known as Kalevalahammer. Jackdays mantains many interesting projects, and one is to list some of the history of Warhammer.
I haven't checked it for accuracy, but knowing Jackdays there are good odds of it being spot on accurate. It would be cool if we could get stuff like the WFRP mailing list, launches of prominent fan sites and the publication of individual issues of Warpstone in there too!
