The trend of more moderate growth for ebooks in the U.S. in 2012 abated slightly in Oct. as sales of adult trade ebooks were up 41% versus the same period last year — more than the 30.7% growth ebooks showed in Sept. It’s still much less than the triple-digit sales growth seen in ebooks in previous years. Growth in children’s ebooks continued to moderate to a 42.4% growth rate in the month, retreating from early-year triple-digit gains.

Ebook growth continued to slow slightly across the book trade in August as children’s ebooks retreated from an early year surge that saw the segment up in triple digits. Children’s ebook sales only grew by about 50% in August; ebooks sales for adult trade books was up 34%, according to the latest numbers from the Association of American Publishers.

Growth in children’s ebook publishing revenues in the U.S. showed signs of slowing from a stupendous rate earlier in the year, perhaps affected by the Hunger Games ebook sales tapering off. Adult trade ebook growth in July was in line with figures from the rest of the year which show a steep drop-off from triple-digit growth rates of the past few years, according to new figures from the Association of American Publishers.
