Overall domestic net sales of professional books, which include material published by nonprofits, such as professional societies, rose last year, as did all publishing categories, according to the Association of American Publishers, New York.
AAP reports that professional books sales increased 5% in 2010 over 2009, to $812.9 million. Total book sales increased 3.6% over 2009, to $11.67 billion.
E-book sales outpaced all categories with a record 164.4% increase in 2010, to $441.3 million (vs. $166.9 million in 2009). E-book sales climbed to 8.32% of the trade book market in 2010 vs. 3.2% the previous year. In other digital platforms, downloaded audio books sales grew by 38.8% to $81.9 million (vs. $59 million in 2009).
"As more formats have evolved and are served by the publishing community, consumers have more choices. These strong sales numbers reflect the efforts of AAP publishers and the response of book audiences," AAP CEO Tom Allen said. Details: www.publishers.org.
