( CNN ) -- Finally , fans of the world 's most famous boy wizard can follow his fight against the evil Lord Voldemort on their e-readers . The entire `` Harry Potter '' series is now available in digital form at Pottermore , author J.K. Rowling 's website for all things Potter , ending what was easily the biggest e-book holdout in the literary world . The books come in a downloadable format that is compatible with all leading e-readers , tablets , personal computers and smartphones -- including Amazon 's Kindle and Barnes & Noble 's Nook . Readers seeking the e-books on Amazon or Barnes & Noble 's site will be directed to Pottermore to buy them . `` For years our customers have loved reading Harry Potter books in print , and have made them the best-selling print book series on Amazon.com , '' said Russ Grandinetti , Amazon 's vice president of Kindle content . `` We 're excited that Harry Potter fans worldwide are now able to read J.K. Rowling 's fantastic books on their Kindles and free Kindle reading apps . '' `` By offering the NOOK editions of this popular series , long-time fans and first-time readers can experience the magic of Harry Potter in a new , exciting way and read what they love , anywhere they like , '' offered Jim Hilt , Vice President of e-books for Barnes & Noble . All seven books in the series will be available in English , at prices ranging from $ 7.99 to $ 9.99 , through an agreement with Pottermore . Rowling did n't agree to make the books available digitally at all until last year , a full 14 years after the first , `` Harry Potter and the Philosopher 's Stone , '' was published . ( It was published in the United States as `` Sorcerer 's Stone '' the following year ) . `` I wanted to give something back to the fans that have followed Harry so devotedly over the years , and to bring the stories to a new digital generation , '' the British author said last year in an announcement on YouTube . `` I hope fans and those new to Harry will have as much fun helping to shape Pottermore as I have . '' The content side of the Pottermore site , which promises users an interactive journey through the Harry Potter universe , is still in beta testing . It 's scheduled to go live in April . Not always a fan of the latest technology , Rowling famously wrote the Potter series by hand . Through the years , Rowling and her representatives expressed two reasons for being slow to the e-book world : a fear of online piracy and the desire for readers to experience her books the old-fashioned way . The Harry Potter books have sold more than 400 million copies and been translated into more than 60 languages . Tuesday 's e-book launch is the second time Rowling has made news in recent weeks . Late last month , she announced that she 's working on an adult novel -- rumored to be a crime thriller .
'Harry Potter ' books finally come to Kindle , Nook . Author J.K. Rowling had feared online piracy of the beloved texts . Rowling famously writes longhand on paper .
