There are 3 original factory publications that might interest you. None are quite as you describe ...,
1. "Instructions for use and maintenance". This is the owner's manual.
2. "Spare parts catalogue". Which is what it says ..
3. "Workshop Manual". Likewise ..
Are you after all 3, or ...?
As to "a definitive book". Hmmm ... Not sure that's yet been written, or is ever likely to be. However Ian Fallloon's "Ducati Overhead Camshaft Singles" is a good starter, as is Tom Bailey's "Ducati Singles, First Person".
I go here for a lot of stuff. Just look under manuals and a whole bunch of material is available. My search engine tells me that Ducati Meccanica's certificate of authenticity has expired so you may have to force the connection.

For a copy of Tom's book(s), try contacting him direct:
Tom at motyeliab dot com
And as per Rick: René and Sue's site is a good source of copies.
P.s Don't bother with the Haynes manual. It's based on the wide-case models and even if there is some overlap, it isn't really what you want.
There is also a Clymer manual. This is essentially a re-print of the factory workshop manual. Just make sure you get the one with the orange cover as this is the one that covers your bike.
