Editor's Note: The Constant

For this issue's cover story, our James Sturdivant talked to four publishers at the forefront of book app development in order to glean some of their strategies (p. 12). It's a great read, and one that should get you thinking about how your publishing operation might use mobile and apps more effectively.

Elsewhere in the issue, Andrew Brenneman posits that in order to increase ebook revenue, publishers need to increase the quality on their digital products (p. 34); J.S. McDougall provides you with a handy, five-point checklist to consult before you put anything on the Internet (p. 29); publishing legend Nan A. Talese expounds on the value of authors (p. 10); plus we provide coverage (p. 24) from the 2012 installment of our Publishing Business Conference and Expo (publishingbusiness.com), including a profile on Hachette Book Group, who received the nod as our prestigious Publishing Innovator of the Year (p. 23).

Hope you enjoy.
