Recommend a book

[Stafford]

Anyone recommend a book on the history of Ducati.
I'd like to know more about different bikes that have been produced and understand the model names like SPS, and what's 2 or 4 valve.
Christmas is is coming, you never know.............

Also anyone been here http://www.ducatimonster.org/downloads.html
interesting downloads including the Ducati font.

Cheers
