In reply to kevinroet:
Aosta is in Switzerland! If it is alpine (rather than rock) guides you are after, then in English Martin Moran's 4000m guide had an update in 2007, and the AC Oberland guide was, I think, updated in 2003. There are various guides on the SAC website in French and German, mostly since 2000. The Italian CAI/TCI definitive guides are mostly a bit more dated but wonderful book (almost works of art), and still packed with usable information.
