The charity 'Healthy Planet' have a great free bookshop down on the Kingsway. The company operates by saving books no longer needed by libraries and other charity shops and offers them back to the reading public for free. They also accept donations.
The books are mostly in great readable conditions and you can find a wide variety of reading subject here from various decades. Run by volunteer staff, the opening times are a bit hit and miss, but the place is definitely worth checking out. You might be surprised just what you might find in there.
