The IDPF, in conjunction with the AAP, has announced trade ebook sales for the month of April were $3.4 million, up 19.9% over the same month a year ago.
As always, they note, "Retail numbers may be as much as double the above figures due to industry wholesale discounts." The data is collected from 12-15 publishers and covers the US market only.
While ebook sales remain paltry compared to the overall book market, we continue to view such growth as further validation that ebooks are are on the rise and will continue to account for an ever-increasing percentage of the book market.
I believe the sales figures *do not* include sales of Amazon Kindle titles. Can anyone confirm this?
