Book Crossing

Book Crossing is not new, but I still thought it worth a mention.

Wikipedia Provides a fairly comprehensive article here.

The sites blurb gets the point across

Where books have adventures of their own. BookCrossing is earth-friendly, and gives you a way to share your books, clear your shelves, and conserve precious resources at the same time. Through our own unique method of recycling reads, BookCrossers give life to books. BookCrossing books are not stagnant dust collectors, but living entities travelling the world as true BookCrossing emissaries. Our books find new readers and introduce them to the wonders of BookCrossing.

Book crossing is not just a site though, Its an idea. I like the idea for years i have sent books to friends, charity shops or just left them in a cafe to see how long they stick around there.

Book crossing adds a social element and method to track these books. The site is starting to look and feel dated missing out on social elements like twittering updates,  and obvious tracking options like mapping the locations in API resource such as Google.

But in general the idea is sound, set your book free, let some one find your story and spread it.
Ecological friendly and interesting results. The sites popularity s waned but I'd like to think the concept keeps going.
