Isn’t that a beautiful idea? If you haven’t done so yet, visit Bookcrossing. I won’t explain, just go have a look.
I’ve been a member for months, registered my books weeks ago… Meant to release them but got sidetracked a bit… I’ll go release a few next week for sure. I have to. It’s too good an idea.
I released only one and someone catched it a couple of days later. I hope he releases it back once he’s done!
