This is such a wonderful convenience. I use it constantly.

Smashing add-on for readers and students. The tedium of going to the library website and investigating availability is over. I use this both from organic and context-menu search results to view two libraries' results at once to see how I can get the book or download fastest. If you can read this, you need this extension.

It's so convenient to see my libraries' holdings when visiting Amazon or Goodreads! I listed two libraries as well as Hoopla. The plug-in's response is very fast.

I had a technical support question and was answered within the hour! I'm very appreciative.

This is by far the most useful extension I've ever downloaded.

WOW!! I have 10 different (all legal) library cards. When I wanted a book I used to have to log into each library (Overdrive app) and search for the book I want. This is amazing. It saves me so so sooo much time. And I know exactly which library to log into to get the book I want. I just wish I had known about this extension sooner!! 10 stars!

Great extension. Superb support. Why isn't this and many other fine extensions usable by Firefox android. This extension is the ONLY reason I use(d) Firefox on my Androids. Kiwi is faster and Puffin works with problemation CMS's better than FF.

My favorite extension! It makes quick work of my library's multiple databases and sources. After 3 years of using it I'd like to repeat that it's such a great idea and a great time saver. The shortest path to a desired book is Library Extension!

Thank you for one of the only working tools to connect to my not-always-well-connected local library (not in WorldCat etc.).

I love, love, LOVE this extension. It is so convenient to be able to search for new books in one spot (I use goodreads, but it works on amazon too! amazing!!) and be able to check the catalogs of all three library systems I am a member in.

Thank you so much for this fantastic extension!

Great Extension, I use this all the time when checking on book from my library.

The most valuable plugin I've ever used. Makes it easier to use my local library!

This extension is invaluable, simple, and saves so much time when viewing a book on Amazon and Goodreads instead of having to also check it against my local library's catalog.

Love it.

I love this as it allows me to look at my Goodreads and know whether books are available and in what form. I suggest it for anyone who likes books and libraries.

Great! Helps me support my library rather than spend money where possible. Works on amazon, goodreads, etc
