I am interested in compiling statistics about the types of ebook formats being purchased. I understand that an author’s royalty statements which include ebook sales are broken down by format (via a different ISBN). If you want to share, even anonymously, that would be awesome. I’ve set up a new gmail account: firstname.lastname@example.org.
What I would like is a breakdown of the formats. I.e., Romantic Suspense Book A sold 5 kindle units, 5 mobipocket, 3 ereader, and so forth. You can send me a jpeg of your ISBNs if you like or you can just tell me the units. Whatever you feel comfortable with sharing. I don’t want to know the value of your royalty, just the number of units sold, if that is something you want to share. If you think this is intrusive, obviously, don’t share the information.
The reason I am asking for this information is that I am interested in seeing to what extent the ease of purchase is making Kindle the better option or whether iPhone readers are gaining in prominence and so forth. Thanks guys.
