The Digital Book World E-Book Best-Seller list tracks e-book sales ranking and price data across six major e-book retailers with the goal of providing the most accurate picture of which e-books are most often purchased by consumers and at what price point. The full methodology is available here.

When news that Robert Galbraith is in fact a penname for accomplished author J.K. Rowling leaked to the press earlier this month, sales of his first book The Cuckcoo’s Calling increased drastically.

Prior to the news, sales of the e-book version were reported to be around only 7,000. This week, the title tops DBW’s ebook best-sellers list.

Does this mean celebrity sells e-books? It’s more likely that celebrity founded upon a track record of good writing sells e-books. And the intrigue of it all certainly didn’t hurt matters.

After all, The Cuckoo’s Calling is a crime drama, complete with a main character who’s a private eye and a mystery to be investigated.

The Galbraith / Rowling’s title, from Hachette’s Sphere imprint, knocks ebook publishing powerhouse Penguin Random House out of the top position on DBW’s list. The publisher has nine titles on this week’s top 25 e-book best-sellers list. That’s two fewer than the previous week.
