NEW YORK (AP) -- Harry Potter has joined the Kindle lending library.

Amazon.com announced Tuesday that on June 19, the e-book editions of J.K. 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.

Financial terms were not disclosed for the online retailer's "licensing agreement" with Rowling.

Rowling only recently permitted e-books of the Potter series and has been offering them through her own Pottermore website. The e-books on the Kindle will be available in English, French, Italian, German and Spanish.
