I have recently discovered Read It! Swap It! A free website where there are currently 37672 books available for swapping with your unwanted books. You agree a swap by someone asking to swap a book with you and you choosing one of their books, or you browsing the library and requesting a swap with someone who will browse your books and either agree a swap, or there is the option to reject a swap if none of their books take your fancy. Books are posted between members, and your postal address is kept secret until a swap has been agreed. This system only operates in the UK. Since joining last week, I have had 10 agreed swaps, and received my first book yesterday. What a fun and economical way to reuse books. Come along and swap a book with me!
