E-books' Impact on ROI

"The market for reference- and information-based publishing in print is small and getting smaller," Potash says. "We are seeing [the use of those materials] migrating to online and

e-book formats."

With double-digit growth and sales of e-books rising each quarter, it's safe to say many publishers are displaying a strong commitment to e-books. And the number of devices that can be used to read e-books—from handheld computers to smart phones have increased, and new digital ink devices improve the experience for readers. These are all positive signs that the future for e-books is now.
