In the adult category, sales for the nine months were down 3.3% with sales off in all print formats and down 0.1% in e-books. E-books accounted for 29.0% of adult trade book sales through September 2014 compared to 28.1% in the same period last year. The format accounted for 14.2% of sales in the children’s/young adult in the first nine months of 2014, up from 11.4% in the same period in 2013.
