Man I agree with everything but that book.
It sucked I use it to hold my laptop of the base of the table. Very confusing and very hard to follow, but I did like the section on the mouth shapes and muscles.
I read all the other all the time.(apart of mikes - which I don`t have yet)
Another good book was this
Game Character Development with Maya (New Riders)
Which I picked up from siggraph, read on the plane back and followed very quickly when I got home.
I also read the art of rigging vol 1,2 and 3 a lot.
They cover all things a rigger will need as well as a few extras like hair,fur,cloth and matt painting.
my graduation prez from my mum (She didn`t think of getting me them while I was in uni
But on a whole I find video tuts the way to go - as long as they are not boring ( **gnomon**)
