One guy that doesn't work for the company anymore declared that the lore of the company is dead? We all must immediately delete everything on our pages? :P

In-game references and books are sources that I consider to be canon.

Then, the other ones like the Gary Noonan and Kirkbride texts.

Then, the ones on important sites like the Imperial Library. (These are still often fan-made, however, like the Imperial Census).

All of those that weren't directly in the games themselves get the Out-of-Game tag on them. That one is there to let users know that it is, like Kirkbride wants, to be considered canon if it fits in with your own view on the series itself. (Even his own work, if you so desire, but I think we all accept Chim, the Godhead and all the rest of it as a given by now).
