BookCrossing - The World's Biggest Free Book Club - Catch and Release Used Books
Just signed up to participate in Bookcrossing after finding the site on Postcrossing where I recently sent a postcard to the Netherlands.
I like the idea of a random book being found just when I need it. Click the title above to learn more and join. Right now, I'm the only one playing in Niagara Falls, NY.
Here are the simple instructions, as posted on the website:
Grab a book, any book.
Register it with www.bookcrossing.com and jot its unique BookCrossing ID (BCID) down in the book, along with the website url Get nifty labels here or here. (If it's already a BookCrossing book, you can skip this step.)
Read your book and then use the BCID to make a journal entry on it. You'll find a place to do that here on the home page or through the link on the left side bar.
Release the book out into the wild and wait for it to write home to you. (You can also give the book to a friend, send it on a book ring etc-- just be sure to make a release note on it when you send it off into the world.)
Sounds fun, doesn't it?
