Regardless of how you get to an eBook in OverDrive, the borrowing process is the same:
After locating an eBook click Borrow. If you're not already authenticated as a Stanford user, you'll be prompted to login with your SUNet ID and password.
Select how you would like to borrow the eBook. Most are available to read as a Kindle eBook or to download as an EPUB eBook. If you don't have a Kindle, you can download the free Kindle app on most devices.
