"Students are more mobile today. Their expectations of being able to get digital content is certainly much higher than it has been in the past," said Scott Criswell, product manager of online delivery systems for the higher education unit of McGraw-Hill Cos., one of the three biggest textbook publishers. Criswell said the company now offers more than 800 digital products, most with audio, and that figure has increased by 50 percent over the past four years.
