Though the library is definitely the cheapest resource for readers, it’s not always the most convenient. Your local branch has a limited number of titles available to check out at any given time, while online retailers make millions of books easy to purchase with just a click.
If you want to support your library without giving up your online shopping habits for good, try installing Library Extension.
According to CNET, the desktop plug-in for Firefox, Edge, and Google Chrome will tell you if the book you’re browsing on Amazon (or Barnes & Noble, Audible, or Goodreads) is available through your local library. Once you install it, the extension will ask you to select the most convenient place for you to check out books. If you’re a cardholder at multiple libraries, or if your local branch is part of a larger system, you can select more than one location.
