Looking for a way to kick your addiction to shopping for books online? A new web browser extension might be of help.
Library Extension will show you if books and e-books you search for online are available for free at your local library. Library Extension has been around since at least January 2013, but it just got discovered again in 2020.
The extension, which is available for Chrome and Firefox, is activated after entering your location and selecting libraries in your area. E-book services are also available.
One installed, every time you browse for books at an online bookstore like Amazon, Barnes & Noble, Goodreads, and Audible, Library Extension will pop up and show you if the books are available at your chosen library.
With just one click, you’ll be directed to the chosen library or e-book service page to borrow the book online or join a waiting list.
