I can reccomend The Book Fountain as a great way to borrow English books. It works just like lovefim (in UK) where you make a wish list of books and they get sent to you, and thenyou send them back in the envelope provided (already has stamp so you don't have to wait 3yrs in PO q!)
The service is great and not too expensive either. Here's the link www.book-fountain.com
