Publishers launch first digital-only textbook for K-12 — from Mashable.com by Sarah Kessler

Excerpt:

McGraw-Hill launched its first all-digital, cloud-based textbook for the K-12 market on Monday at the International Society for Technology in Education (ISTE) conference.

Unlike the company’s previous digital efforts for this age group, the books are intended to be used as primary texts (other McGraw-Hill digital texts have been sold as a companion of physical textbooks). This is the first time a major publisher has launched such a platform.
