Sales for U.S. print and electronic books are up overseas, with the digital market increasing fourfold since 2010.
According to a study from the Association of American Publishers released Friday, revenues for exports not including Canada increased 7.2 percent from 2010 and 2011 despite the economic slump in Europe.
Total revenues were $357.4 million in 2011, with e-sales jumping from $4.9 million in 2010 to $21.5 million. The study includes reports from 161 publishers, including the biggest six: Random House Inc., Simon & Schuster, Penguin Group (USA), Macmillan, HarperCollins and the Hachette Book Group.
The association credits the rise to the overall boom in e-books and to the expanded market for U.S. books in foreign countries.
