Do not close the ebook to look at another book or adjust a setting. Change your Nook to be on airplane mode so that you don’t drain the battery as fast (and because this may cause it to turn off the library book like rebooting it would). Rather than powering off your Nook, only let it sleep. Do not hook the Nook up to the computer or otherwise charge it.
According to one commenter, this will keep the book from expiring. Of course, you’ll eventually have to charge it, but if you’re lucky you should be able to get it done before you’re done reading. A better idea is to always check out your Nook ebooks for 21 days, since you can return it if you finish early. And do return if you’re done early because it’s kinder to everyone.
