Apple is partnering with McGraw-Hill, Pearson, and Houghton Mifflin Harcourt on the textbook front, with the three companies currently responsible for 90% of textbook sales in the United States. McGraw-Hill and Pearson are rolling out a handful of introductory titles today, with more coming soon. 
Apple's initial focus for its textbook effort is on high school textbooks, with books priced at $14.99 or less. Authors can continually update their content, and the students get to keep their copies indefinitely.
