Last week the Association of American Publishers (AAP) released news regarding January 2011 book sales – saying that e-book sales are up 115.8% since January 2010. Downloadable audio books also rose, but at a much smaller rate (8.8% over the previous year).

Overall, total book sales dropped on all platforms by 1.9%. The biggest hits were to the adult mass market (down 30.9%) and adult and children’s paperbacks (down almost 20%).

The two areas that seemed to grow over last year were sales of religious books and professional/scholarly books.

While e-book sales are definitely still on the rise, they still account for less than 10% of total book sales. I’m sure this will change over the next few years as the publishing industry attempts to work out pricing models and licensing models for the e-books.
