image The guy in the photo is reading off another gizmo rather than the Kindle—whatever is on the screen, be it a book or a calendar. And in fact I suspect that the K machine will be just one e-reading platform. But it still could do very well over the long run.

Short term? Kindle book sales may have doubled in the past two months. So says the Time site, repeating the lowdown from an Amazon insider. Read the item for full context, such as the fact that we’re talking about some tricky percentages, not solid unit sales figures. But here’s the fun stuff:

"According to a source at Amazon, ‘on a title-by-title basis, of the 130,000 titles available on Kindle and in physical form, Kindle sales now make up over 12% of sales for those titles,’" writes Time’s Josh Quittner.

"Amazon is notoriously tight lipped about sales data, and the new line of business that the Kindle represents for the online retail powerhouse has been especially frustrating for analysts and media to parse. At a technology trade conference in May, CEO Jeff Bezos said that Kindle sales accounted for 6% of book titles sold for the Kindle and in print. So Amazon appears to be selling more e-books."
