The idea is that you choose a book you love, print off one the BookSwap stickers like this, write a little note to the new owner about why you love it and leave it somewhere to make someone's weekend! It's that simple :)

My copy of 'Captain Correlli's Mandolin' was supposed to be hanging out in Leeds train station yesterday evening but when I went through, there were a lot of people a few too many fizzy pops into the night and so I took it home with me again! It will instead be left somewhere in Leeds City Centre today while I'm out and about!
I'll be posting pictures of the drop on Twitter this evening (which, incidentally, I am irretrievably addicted to!) using the inventive username @litaddictedbrit!
[Oh, and all the pictures are taken straight from the Guardian's website - thanks Guardian :)]
