Amazon

What sets Amazon apart from renters is that you can actually choose the exact lease term and pay only for a specified period of time. So, if you're taking an auditing class, or know that you only need a specific textbook for a short period of time, this is a great and financially effective choice.

You will also have access to a number of e-tutorials that you can view free of charge during a 7-day trial period. Amazon's XRay capabilities (available on the Kindle Fire HD and the free Kindle app) allow you to search for words in a dictionary, translate text, and even search for relevant information from sources such as Wikipedia and YouTube.
