Kindle and other e-books for Italy

I'm looking for recommendations of Kindle edition or other e-books that people have found useful or enjoyed for leisure about Italy. This includes guidebooks, classics, memoirs, history, food, etc. I am not looking for paperback and hardback edition recommendations. I'm not taking any paper books on my trip this year except for a few phrasebooks and food companions that I expect to carry with me and use each day. I have guidebooks pretty well covered (Rick Steves, Rough Guides, Lonely Planet, Frommers). The biggest problem I've run into is that most books from recommended reading lists simply don't exist in the Kindle or e-book format. Almost all the books from Rick's list aren't available, at least not on Kindle. I have some classics like Machiavelli, but the problem I've run into on classics is trying to decide which edition to get. There can easily be ten or more editions of the same book and it isn't generally clear which is might be better than another. If you recommend a classic, please list the date or price or anything else that might distinguish the edition you are recommending. For example, "The Civilization of the Renaissance in Italy" by Jacob Burckhardt shows at least 10 Kindle editions. Anyway, if you have some suggestions of digital books I can find for free or buy for my Kindle that you've enjoyed about Italy, I would love to hear about them.
