fyi, the library by my home has a "free" book section. Each book has a large label on it indicating that it is a traveling book.

The idea is that if you take a book, you log onto a website and enter your city/state, and then drop off the book somewhere else, perhaps at the end of a flight. Someone else can take it, log it, etc., and the cycle continues.

For newspapers, I see them being traded around alot on flights already.

I like it, but some wet-blanket in the airline's legal department would point out that some customers would make a fuss if they encountered "objectionable" or "politically slanted" material on offer.
