Harry Potter e-books to be offered for free through Kindle

Harry Potter has joined the Kindle lending library. Amazon.com has said the e-book editions of JK Rowling's seven Potter novels will become part of the Kindle service available to Amazon Prime subscribers.

Members can download a book for free once a month. Amazon's library has more than 145,000 books. The e-books on the Kindle will be available in English, French, Italian, German and Spanish.

Financial terms were not disclosed for the online retailer's "licensing agreement" with Rowling. The author had only recently permitted e-books of the Potter series and has been offering them through her own Pottermore website.
