"a web start-up leaping into a nightmarish logistics problem to make life easier for its customers. The US venture has amassed a multi-million-volume library of new or near-new textbooks, which it rents out to students at college campuses throughout the country. Rental periods range from one to four months, and the savings for students can reach 75 percent of a book’s retail price. Adopting the increasingly popular ‘Netflix model’, BookRenter offers students convenient delivery options and lets them return books by UPS at no charge. Rental terms can be extended as needed, and students can also decide to buy a book if they’d like to keep it.
Of course, BookRenter must compete with established campus retailers, as well as new ventures that are offering free textbooks sponsored by advertisers." (http://www.springwise.com/media_publishing/textbook_rental_for_college_st/)
