Which brings up the question of how much stock to put into the sourcebooks, since they, as is traditional in BT, are subject to in-universe biases and tampering.
That's true, but as Knightmare mentioned, new trumps old in terms of canon. And sourcebooks sit at the top of the heap (as they absolutely should). The novels (as much as folks like to claim the whole third person omniscient thing) are some of the most biased sources in the entirety of BT material.
