I think I might have found the perfect charity!  Book-Cycle [http://www.book-cycle.org/]  They collect unwanted books and make them available to the public and collect donations in return – the money is used to help communities in developing countries by providing educational resources.  They also collect unwanted tree saplings, promote wildlife issues and encourage reforestation of rural England, provide free trees, and information on self-sustainability and self-reliance (e.g. growing your own food). They’re even involved with independent film screenings, and art exhibitions.  Could these guys tick any more boxes??!

There’s only one downside I can see – they’re based in Exeter, so a bit of a trek for me at the moment.  Still, when we move to Exmoor….  😉
