Hi, I was pleasantly suprised to find the Works of Ennemond Gautier ("Oeuvres du Vieux Gautier") available on-line on the CNRS editions web-site. You can order them here: http://cnrseditions.fr/ouvrage/3510.html (with the help of a little French...)
The price is ridicoulous and the shipping super-fast: I had them in 5 days. My 2 cents, Luca To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
