As a book lover, I have the lovely task after Christmas of lugging a small bookshop back home with me on the train. Because books are easy gifts to give, aren't they?

But what do you do with your books once you're done? Put them on the shelf and forget about them? Me too. There's only a handful of books that I reread. So the rest are there just gathering dust (and possibly making me look clever to anyone who comes for tea).

I'm excited to discover Read it, Swap it. It is, like the very best ideas, very simple. You upload the books you're willing to play swapsies with. Find one you like and message the owner, they'll nose through your stuff and pick what they want, and then you'll swap! You can that book you've been meaning to read, or find something new, and you didn't have to go and spend £6.99 in Waterstones.

Once you've got the book, you can rate the other user like you would on eBay. That way if someone is getting lots of books but not sending them out, they'll be outed very quickly! You can also swap more books if you have more positive feedback so it's a great way of stopping bad behaviour.

If you've got a lot of great books you know you'll never read again, this is a great way to exchange them for something you'll use. Postage will only cost you a pound or so, and you'll get hours of happy reading time while it's cold outside.
