Matt MacInnis, a former Apple employee, is behind a new start-up looking to bring collegiate textbooks to the iPad. The Wall Street Journal reports that MacInnis’ company, Inkling, is set to introduce four full-length interactive textbooks on the App Store. The books—McGraw-Hill’s best sellers in biology, economics, marketing, and psychology—will include features like 3-D views, video lectures, and interactive quizzes, while allowing students to highlight text and take and share notes. According to the report, Inkling has already made deals with other major publishers, including John Wiley & Sons, and Cengage Learning, to launch new titles. Prices for McGraw-Hill’s first titles are expected to start a $2.99 per chapter or $69.99 per book, with prices increasing over time to $3.99 per chapter and $84.99 per book.
