Print still dominates but e-books grew from 17% of sales in December to 21% just two months later in February, according to this new study from the Pew Research Center. Authors will be pleased to learn that e-book device users read more: "Those who read e-books read more books than those who don't have the devices: The average reader of e-books has read 24 books (the mean number) in the past 12 months, compared with an average of 15 books by a non-e-book consumer."
