Break out your iPods: Harry Potter is going digital. JK Rowling, once publishing’s greatest holdout against the computer age, has made all six Potter novels available for audio downloads. In a message posted Wednesday on her website, Rowling said she was concerned about online piracy, included bootleg editions for which the original text was altered. “Many Harry Potter fans have been keen for digital access for a while, but the deciding factor for me in authorizing this new version is that it will help combat the growing incidents of piracy in this area,” Rowling wrote.

“There have been a number of incidents where fans have stumbled upon unauthorized files believing them to be genuine and, quite apart from the fact that they are illegal, the Harry Potter content of these can bear very little resemblance to anything I’ve ever written!” The digital audiobooks are being released by the Random House Audio Trade Group, her current audio publisher. They can be purchased through Apple’s iTunes store, for prices ranging from $32.95 for a single book to $249 or the whole series, which, according to Random House, includes a “full color digital booklet” and “previously unreleased readings” by Rowling. Neil Blair, a lawyer with Rowling’s literary agency, said on Wednesday that there are no current plans for Potter e-books.

But up to now the author had only permitted paper and traditional audio releases, making her work a favorite for online pirates, although illegal sales are believed to be relatively tiny. Helped by the iPod boom, digital audiobooks are already one of publishing’s hottest sectors.
