I have this one:
which I bought years ago from a book club. It has loads of stuff in it, and there's a Porsche 917 version too. Unfortunately the Ferrari book I think is long out of print and would appear quite expensive, certainly on the Bay:

May be worth looking in 2nd-hand shops for it.
There's also one of the big Konemann-published books called Ferrari with Schlegelmilch photography (sorry I don't have an image of this) which should be fairly easy to find, and there's a new prototype book out:
which looks quite interesting.
