Good training books for Tri and marathon/ultra running

Im looking to pick up a couple more books on tri training and running. Ive read the usual Going Long, and Triathletes training bible. Im a bit more curious on what else is out there besides those two usual that everyone suggests. Id like to learn a bit more on my own this fall/winter on training for distance, tri and marathon/ultra. Id like to get a bit stronger on the bike to. Not sure if that fits into tris, or a whole seperate issue on bike training.
I can find a lot on line, but its kind of a long shot on what would be helpful, or what would just tell me what I already know since Im not a beginner. So give some suggestions!! (some more casual reads of good running/tri books is ok to)
