My local library has never heard of Ayn Rand.
'Atlas Shrugged' here is divided in three volumes
'La rivolta di Atlante - il tema'
'La rivolta di Atlante - L'uomo che apparteneva alla terra'
'La rivolta di Atlante - L'Atlantide'
You can order them on online bookstores (like Amazon.it), but none have them in stock. Last edition was published in 2007.
It's quite fun that a book so important and controversial for the American culture is virtually unknow outside U.S. borders...
