There is a good new ampelography in Italian by Antonio Calo titled: Vitigni d'Italia.  The book is over 800 pages long and it includes variety descriptions, pictures of fruit, leaves and shoot tips, lists of clones in Italy for each variety, clone descriptions, and information about where the varieties are grown in Italy. I think it was under $50 including shipping from Italy. It can be ordered from http://www.internetbookshop.it. I had someone who spoke Italian help me order because this internet site is all in Italian.
