A few images from our campaign with The Guardian & The Observer for their Books Season.

Part of the season is the Book Swap initiative, which encourages people to leave recommended books for others to find, using these stickers.

Ben T left Roald Dahl's autobiography for someone to find, apparently somewhere in the seafaring 16th century.

Many others left books and posted pics on Flickr to help others find them.

Lots of chat on Twitter…

Wish I'd been in a position to find this one. A hammock on Grand Cayman with a copy of (the rather excellent) Poisonwood Bible, just waiting for someone. Nice.
