Textbooks are coming to the Book section of the Google Play store, Google announced at its breakfast event this morning.

Android users will be able to rent or purchase textbooks from all five of the major academic publishing houses. Rental periods will be for six months and will be discounted up to 80 percent from their normal purchase price.

Users reading Google Play textbooks will be able to search through the full text, create bookmarks, and highlight passages. Additionally, a "night reading" mode will keep things readable at low light levels—something to help students power through late-night cram sessions without waking up their roommates.

Textbooks will be available on the Google Play store in early August. Detailed pricing and specifics on the exact titles available have not yet been announced.
