Subject: Travel Guides
I am a bit late on this thread, I know, but I was traveling:-)

For really in-depth historical and cultural information, I like the Blue Guides. They have several for Italy, from a single guide for the country to guides for Northern, Central, Southern to guides to regions (i.e., Tuscany/Umbria) These guides are not very good for hotels and restaurants, in my opinion, but the people who write them travel the area over a long period of time and come up with incredible detail.
