Jim, you'll never find e-book sales data because the only reported data is for Big Six publishers or stuff run through Bookscan, and there is probably MORE activity outside the system than in. When you consider free downloads on Scribd, Smashwords, Feedbooks, et al, sales by individual author sites, indie authors selling through Smashwords and Amazon, established authors selling their own backlist through all outlets, and plain old direct sales or deliveries, the only real data you ever see is a very narrow snapshot taken by a lens pointed in only one direction.
Remember back when Apple was claiming a fourth of all ebook sales? Yeah, riiiight. Statistics are lies manipulated by whomever is presenting them!
