With consumers pulling back on in-store book purchases lately, Random House may be picking a good time to ramp up its ebooks offering. The publisher is expected to increase the number of ebook titles it has to 15,000 from the current 8,000, the LAT reports. Although ebooks represent just 1 percent of total book sales, that could change as both publishers and consumers adjust their habits in the current economic climate. Wider adoption of e-readers like Amazon’s Kindle could help too, although the dismal financial picture could depress growth there as well. Matt Shatz, Random House’s VP for digital operations, is crediting the Kindle with driving ebook sales’ growth by triple-digit percentages this year. He declined to offer the LAT any specific figures, indicating that the revenues and sales units are still comparatively small.
