I just returned from a week and a half in Florence and am already craving real italian food, not the oversauced american versions. In particular, ribolleta and a good ragu or any other recipes you would like to share! Or if you know of a great website or book I should check out point me there too.
I recently picked up a used copy of Marcella Hazan's More Classic Italian Cooking. Haven't made anything from it yet, but she seems to put the emphasis on authenticity, with modifications where necessary to adjust for the availability of certain ingredients in North America. She's written numerous books you may want to check out as well. There are a bunch of her recipes available online here:
There are a number of threads on Marcella Hazan's wonderful ragu, as well as a number of threads from when her book, Essentials of Italian Cooking was the 'Cookbook of the Month':

Two books I highly recommend are "Eat Right - Eat Well the Italian Way" and "Italian Family Cooking" both by Edward Giobbi. Not only is Mr. Giobbi is a James Beard award winner and a culinary professional, he is also a well respected fine artist. His books are full of the recipes Italian families live for and have been cooking for generations.
