I read an article this morning, thanks to link posted by a fellow RWA member, about the fact that from early next year, the New York Times will have a separate bestsellers list for e-books. The NYT bestsellers list has long been the pinnacle achievement for authors. If you're a NYT bestseller, then you've really made it. The new bestsellers list is good news for people whose books are only available by e-book format. Of course, I imagine most of the time, the e-book bestsellers list will mirror the print bestsellers list, as now most big name authors who publish with the bigger publishing houses have their books available as e-versions as well. But, I can see that occasionally, a little-known author from a smaller e-pubbing house, or even self-published via kindle, will have a cult hit that'll climb to the number one spot, knocking those big-names clear. I would have to assume this would open up all sorts of doors for that author. So, in some ways, this development could change the outlay of the industry as we know it now, by subtle degrees.
I'll be keeping an eye on this, to see how it all pans out.
