The Association of American Publishers (AAP) reports that ebook sales rose 146.9% in May, which is even more dramatic when compared to the drops that all major adult print segments experienced. This continues the trend from April, when ebook sales rose by 157.5% while print segments declined.
I’d be curious to see sales numbers for self-published ebooks, which I don’t think are included in these monthly reports put out by the AAP. Although all I have to go on right now are anecdotes, Joe Konrath admitted that he and at least a few other self-pubbed authors saw sales of their ebooks drop in June.
