I came across this unique site. It is a great way to share your books, without really expecting anything in return, except for good karma. There are a lot of book exchange or barter sites out there, but this one is unique. With this system, you release your books to the wilderness and you can track the movement of your books. I think it is a great way to go about it. Check out bookcrossing. You’ll love it. And if more people join this from Sri Lanka, this will take off. So I am doing my bit to promote it here.
