It took much longer that anyone expected, but J.K. Rowling has finally opened the digital doors of her Pottermore Shop, allowing fans to buy e-book versions of all seven Harry Potter novels.

Rowling announced her online portal, Pottermore, in June of last year and promised that the site would provide "an exciting online experience around the reading of the Harry Potter books," as well as the future sale of e-books.

By selling the books through her own site, Rowling will keep a majority of the profits, with only publishers Scholastic and Bloomsbury sharing in the profits. The series has to date sold over 450 million copies and has been translated into more than 70 languages, making it one of the best-selling literary properties of all time.

The first four books in the Harry Potter series are retailing for $7.99 while the latter four, which are longer, are going for $9.99. The e-books are compatible with all major e-readers including the Amazon Kindle.
