Dear vihuelists, Thanks for all the information. I searched at Omni and found the book. I think it is out of print but there must be still some copies around...
I do live in Brazil (libraries here do not have this book), so I'll probably buy it from Omni. Best wishes. -- To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
