I picked up this book while I was in Venice. It seems to be a brand new release and seeing as though it is a heavy 700 page mother I figured it was worth the 18 euros price tag just to avoid paying postage if I bought it online. It is obviously in Italian, which is somewhat of a drawback for someone like me, but as it is set out as a dictionary of the films it is primarily a resource with cast lists, key personel, dates etc so I can make sense of most of it. It also has other articles and stuff which I will have to work on translating but on the whole it looks pretty good. If nothing else it should be useful as a cross referencing tool to try and avoid posting errors on this site gleaned from other books.
I'll give an update when I have had a chance to look it over more thoroughly.
If anyone is interested, it is published in Milan by Oscar Mondadori.
