Just wanted to give a plug for the Libby app by OverDrive.
Borrow ebooks, audiobooks, magazines, and more from your local library for free! Libby is the newer library reading app by OverDrive, loved by millions of readers worldwide.
Works great with the Kindle App on an iPad. Excellent alternative to forking over full price for an eBook you might not be sure about.
Also, public libraries everywhere and their staffs deserve all the love they can get.
