That book you want to purchase on Amazon or Goodreads? It might be available to borrow from your local library!
Chrome's "Library Extension" lets you check your local library immediately, while you're in Amazon or Goodreads. [Note: As of this publication date, also available at Barnes and Noble, AR BookFinder, and Google Books! ]
How cool is that?!
I made this mini slide tutorial to demonstrate how the extension works.
