JK Rowling has revealed today that she will self-publish the ebooks to her successful Harry Potter series through her newly-announced proprietary platform, Pottermore.
Rowling stands to make significantly more money by selling her e-books directly than if she sold them through her publisher. Authors generally get anywhere between a few and 10 percent of royalties from printed book sales and anywhere between 20 and 40 percent on e-books.
If they self publish through the likes of Amazon, they can get as much as 70 percent of revenues (with the remainder going to the e-book store). Selling direct to fans also means that Rowling will benefit from demographic data and contact details traditionally safeguarded by the publisher or retailer. This information will be invaluable for promoting new projects and for building a mini merchandising empire.
