J.K. Rowling’s slow, inexorable slide out of retirement continues. As we noted a couple of months ago, “For someone who’s not writing any more books about Harry Potter, J.K. Rowling sure is doing a lot of dabbling.”Earlier this year, we wrote about one of Rowling’s post-retirement dabblings, the production of seven handmade copies of Beedle the Bard, a book of “wizarding fairy tales” referred to in the Harry Potter series. Amazon spent $4 million on a copy, and then used it to market a writing contest. Part of the prize, incidentally, was the opportunity “to spend a weekend with the rare and delightful book of fairy tales (security guards included, of course).”Now that prize doesn’t look quite so exclusive, as Bloomsbury and Scholastic have made an edition the book available for the masses for just $7.59 and arriving in early December, just in time for the holidays. Amazon is going one further, offering up to 100,000 pricier facsimile “collector’s editions,” with “a reproduction of J.K. Rowling’s handwritten introduction, metalwork and clasp, and replica gemstones,” as well as various other accouterments.All net proceeds go to a charity co-founded by Rowling.
