The 4-year-old textbook rental giant has branched out into digital textbooks today with the launch of its newest service.

Chegg now offers you the chance to rent an HTML5 based digital textbook. The textbooks are browser based, and they work in most web browsers including Chrome, Firefox, and Safari. Chegg is promising the usual basic textbook features like notes, highlighting, search, copy, and print. But there’s also a downside; the textbooks require a live internet connection and (less importantly) you can only have them running in 1 browser at a time.

Chegg has already signed up a number of publishers, including Macmillan, McGraw-Hill, Cengage Learning, Elsevier, McFarland, Oxford University Press, Rowman & Littlefield, Taylor & Francis, Wiley, and Pearson. The selection is still limited to only a fraction of the total print titles as Chegg  ramps up support for the new servic, and that’s expected to change by the end of the year.
