It's a holiday weekend in America, but they're working in the UK. A story posted by The Bookseller today really caught my eye.
It says that Hachette UK is seeing "nearly half" of its sales taking place online. The report, built around data provided in an annual letter by CEO Tim Hely Hutchinson to authors, reports that ebook sales are about 25% of Hachette's sales. That implies that a third of the print sales (another 25% of the total) are taking place online.
Furthermore, Hutchinson reports that ebook sales for fiction are at 30%, with "some genres and authors" at over 50%! If you assume that the ratio of print sales online remains a third for those subsets, you calculate that for fiction overall online sales are about 53% and for some genres and authors they are close to two-thirds!
