Yep, everything by Ian Watson for a start. (I'd almost rather everything
else have the icon...) Presumably they objected to him including a prominent Squat character, for instance.
William King's
Farseer has it as well. I'm not sure why.
Here's another link on their justification for it, and
here's an interview about it.
However, we are branding some of the books within the PoD range as 'Heretic Tomes'. One of the great opportunities with PoD is to bring back older titles - some of which even pre-date Black Library - that no longer accurately reflect the Warhammer or Warhammer 40,000 universes. These are the kind of novels that we wouldn't want to put on the shelves of a Games Workshop or bookstore because anybody unfamiliar with Warhammer or Warhammer 40,000 might get the wrong idea and come away with an inaccurate picture of our fictional universes.
I find this attitude very worrisome. Is
Space Marine an 'inaccurate' picture of 40k? Are
Draco or
Farseer inaccurate? If even published material can be arbitrarily labelled inaccurate or inauthentic, then we pave the way to an ever-more restrictive, straitjacketed view of 40k background.
