Traveling Book

As I was leaving one of the social centers in town, I saw this book laying on a chair by the door. I picked it up to turn it in but open the cover to find that is was a traveling book. I had never heard of a traveling book so I took it home and went on the web site that was indicated inside the book's cover page. What I am suppose to do is, read this book and when finished, register it on the website and take the book out somewhere and leave it for someone else to find. There was another note that gave a registered number for the book and where it had traveled. I loved this idea and decided to take some of my books and make them travel.
