Those books are very thorough. I haven't looked at mine in a while, but I'm pretty sure Black Cauldron is in there. They had pretty much every Disney animated character. Mine is the one that goes up to Aladdin. It's on my book shelf, but my TV cart blocks it, where all my great books are...

There are some priorities for you, ha. Because I'm a collector, I have stuff everywhere (though I try to arrange it nicely), so moving something (like a TV cart) can cause a domino effect that is a real pain in the patootie.
Anyways, they do need to update it, but it would have to be sooooo huge now, unless they left stuff out, and it wouldn't do to leave stuff out!
One book I greatly regret that I have never gotten (yet) is the old classic, "Disney Animation: The Illusion of Life." Though I have other books on Disney animation. I really need to get that one, but I want a copy that's in mint condition. I wonder if it is in print at all right now.
