I came across this on my other blog and thought it was an interesting idea and thought I would share it here. ^_^
Opps didn't look at the comments till now. Lynn - I have looked at the site you showed me, bookcrossing is different. Your website is to keep track of books you own. ^_^
Bookcrossing is a fun way to register books and share them. You register a book on bookcrossing and then leave it somewhere, anywhere - in the park, in a locker at the gym or just anywhere you think it will find a home - hopefully someone that will be as touched by the book as you were. Leave a note in the book that it was registered in bookcrossing and they can go on bookcrossing and say where they found the book and where they are going to put it. That way you can track where your book is going and hopefully they will put that book someplace where it could reach someone else when they are done reading it.
I thought that was an interesting idea. I am trying to figure out what book I want to put on a journey.
