What is the Library Extension? It is a free extension for either the Chrome or Firefox browsers that will tell you when you browse for books on Amazon (or Barnes & Nobles, Goodreads or Audible, among other sites) if your library has the book and if it is currently available.
How do you use it? Download the extension and install it in your browser (visit the site https://www.libraryextension.com and then click on the appropriate ‘Install’ button).
Once the extension is installed in your browser you need to configure it. To do that click on the icon of a stack of books in the top right corner of your Chrome browser (A similar icon will appear in the top right corner of your Firefox browser too).
In the window, you will first configure what libraries you have access to. These are organized by country and state. Both fields are pull-down menus. Then select the library from the pull-down menu and click on the ‘Add’ button. Add all of the libraries you have borrowing privileges from.
When you have your libraries selected, click on the ‘Sites’ tab. By default, all the choices will be selected. I went through the list and disable those sites specific to countries other than the US.
Now you are ready to start using the extension. Just visit a book site (like Amazon, Audible, Barnes & Noble, Goodreads, or Google). As you browse looking for books, you will see a pop-up on the right side of the page to indicate that the book you are looking at is available at your library.
