I use the free version of Libib.com [1]. Both the Android and iOS apps work just great. The app has an integrated barcode scanner and automatically looks up for the book's info. You can even export the catalog as csv.
Maybe you want to ignore it, but Italy is so much heterogeneous that living here is not always being home: I'm not home. I'm in Italy but I moved away from my place years ago.
It's funny how the same thing can be seen in such different ways. I have been planning since long to go away from Italy and I will eventually go away, but I feel like it's an act of cowardice. You said just the opposite...
I'm from Italy as well. As everyone else, I am dissatisfied with how Italy is run, but it's _disgusting_ to see how many Italians living abroad claim the right to hurl mud at Italy. I think the real challenge is to stay here, not to run away abroad.
As a proof, here we ended up talking of mafia and corruption, following common stereotypes and therefore giving a distorted idea of Italy. I think most of the people that are saying "run away" are implicitly trying to justify themselves for their decision to go away from their country and family.
Sadly, more than in culture, food and wine, Italians are the first for the most destructive self-criticism in the world. I have rarely heard a non-Italian speaking so low of his own country, as only Italians can do.
