New Stats: E-Book Revs Up 153% Over Last Year; Digital Audio Growing, Too

The newest set of statistics from the Association of American Publishers show that e-books saw triple-digit percentage growth again in July, compared to the same time last year. In a bit of good news for print books, adult hardcover sales were up 33.9 percent for July 2011 compared to July 2010. And sales of digital audiobooks are up 26.7 percent so far this year.

Here’s how July 2011 stacked up compared to July 2010. (Hardcover sales were up in June 2011 as well, suggesting that increase relates to summer beach book buying.)

And here’s how sales compare for the first seven months of this year, compared to that period last year.

Note that format isn’t broken out for Religious books in the AAP stats, so it’s unclear from this data whether the growth in that category is primarily on the print or digital side.

The AAP data is provided by 80 U.S. publishers, with 17 of those additionally providing e-book figures. The AAP cautions that its monthly statistics should not be compared directly to BookStats, the AAP’s recently launched joint venture with the Book Industry Study Group, which will include data from nearly 2,000 publishers and will be published annually. Rather, the monthly numbers provide a general sense of broader trends in book publishing.
