This project was launched in 2001 and today has 609,853 members from 130 countries and nearly 4.5 million books, free shuttling around the world.
The essence of this social project as follows: all willing to share their love of reading with others can register on the site www.bookcrossing.com to the base of the book that they are ready to give Global a library, printed label with the serial number, paste in the appropriate book and send ... it to float freely.
You can leave it on a park bench or simply to transfer familiar with instructions, after reading to pass it on. Quite possibly, a couple of years it will be at the other end of the world, and you'll know about it, tracking the movement of books through the site (assuming that it has found a person must be registered on the site.) But even if you can not learn about the future of his book in any case such a project worthy of every kind of admiration.
Incidentally, the draft clearly troubled, given the amount of advertising on their site
