Choose a book you enjoyed reading (or even one you didn't enjoy reading - reading is subjective after all) and leave it somewhere, anywhere for someone else to pick up and read - a park bench, the steps of a public building, the back seat of a bus or a restaurant loo will do fine. Be inventive.
The Guardian is urging us to do just that in a national Book Swap giveaway of 15,000 books. There's no charge for them and the campaign runs until the end of October. You can get a free bookplate sticker from The Guardian and The Observer on Saturday and Sunday or download one online from www.guardian.co.uk/books/interactive/2011/sep/15/guardian-and-observer-book-swap-sticker. Insert a sticker in your giveaway book and write a message for the finder, then drop the book wherever you choose to leave it. If you happen to pick up a book someone else has left, leave it for another finder and upload the details of where you left it at www.guardian.co.uk/bookswap or on Twitter (#guardianbookswap). You also have to upload a photo of the book where you found it and to read and review it on www.guardian.co.uk/bookswap. If you don't have a spare book, you can get loads from local charity shops.
Origins of Book Crossing
Seems like fun but book swapping is nothing new. The idea, known as Book Crossing was dreamed up by Ron Hornbaker in 2001. His website, http://www.bookcrossing.com/ has spread its message to more than 113,000 people worldwide. If you want to 'release' books into the 'wild' you have to register on the website and you can go hunting for books listed and their whereabouts. Official BookCrossing Zones can be found in coffee shops, cafes and restaurants and other places. An annual convention in April attracts BookCrossers to literary events where they can release books. In 2012, Ireland will host it in Dublin. London took its turn in 2008.
Bookswap at Endcliffe Park for Open College of the Arts
Here is a copy of One Day by David Nicholls left on the wall of Endlciffe Park in Sheffield. Inside is the message left on the sticker by Elizabeth Underwood from OCA. 'I've chosen the place because lots of people climb over the wall into the park,' she says.
