I love this extension. It works most of the time, and as a person with 3 library cards, I really like that I can see multiple libraries in a clean view.

This extension is easier to use than my library catalog. I often search for a book on Amazon and then check the extension to see if it's availabe at my library. It's a super useful little gizmo!

Very handy, although hard to navigate.

This addon has saved me so much money and encouraged me to support my local library. Absolutely invauable; it's one of the first addons I install on a new device.

Works on PC and Firefox Nightly on Android. Thank you!

Wonderful search tool, scanning multiple libraries for access. Would give it 6 stars if more were to be had

This add-on has saved me money by letting me know if a book on Amazon is available at the local libraries my wife and I belong to. Jeff Bezos gets enough already from me!

I love Library Extension, and when I emailed them with something that wasn't working, I not only got a reply from the creator, but he fixed the problem. Wow!

I didn't expect to use this extension but I have quite often. It works great.

This extension is the most useful, saving me from having to search our public libraries when looking at a book online, and in any format. Highly recommended.
