Quoting from an article in Shelf Awareness, an e-newsletter of the book trade:
- E-books leapt 82.9%, to $4.3 million.
- Children's/YA paperback jumped 18.4% to $69.4 million.
- Adult hardcover rose 9.2% to $100.9 million.
- Professional and scholarly rose 3% to $99.8 million.
- Adult paperback edged up 1.8% to $147.4 million.
- Adult mass market fell 4.5% to $70.1 million.
- Audiobooks wound back 6.9% to $11.9 million.
- Children's/YA hardcover fell 9.3% to $96.4 million.
- Religious books dropped 10.8% to $61.1 million.
- University press paperback slid 13.9% to $9.8 million.
- University press hardcover fell 17.8% to $6.4 million.
(I personally think that a good part of that leap in the ebook numbers is in the reporting of them - few print publishers bothered reporting those numbers before, and the AAP does not solicit sales figures from e-publishers.)
The article further discusses the decline in sales everywhere, as reflected in sales figures from general retail stores. Only warehouse clubs and some big box stores (BJ's, Sam's, Wal-Mart) had noticeable sales increases. But Target was down 3%, luxury stores and department stores were down significantly. So the drop in book sales is part of a general consumer cutback in spending.
From Wall Street Journal:
"The September numbers show a nation paring back in the face of economic uncertainty, fleeing extravagance in favor of low-priced basics. Discretionary spending is drying up as Americans grapple with higher food and energy prices, depressed home values and diminished retirement accounts."
