This extension is a dream come true for book lovers. To be able to see at a glance if a given book is available from my local library from within Amazon or Goodreads is so convenient. The developer is very responsive to requests to add libraries, too. I requested that openlibrary.org be added, and just got word from the developer, Andrew, that it was in the latest version. Highly recommended if your read, buy and borrow books.

This add-on works great! I love how you can track multiple sources at once. It's really made keeping up with my TBR pile easier.*

*Disclaimer: By easier, it should be understood that the poster means it makes it easier to find books. The TBR pile itself has grown much worse.

Makes Amazon infinitely more useful! Integrates seamlessly and easily.

An outstanding resource to help access your local library's collection. A great companion to Goodreads and Librarything. Developer is super-responsive in providing support.

I live for this add-on! This has dramatically decreased my impulse purchasing from Amazon for ebooks. Especially the Daily Deal $1.99-3.99 variety. Now I instantly know if my library a few blocks away - or immediate library download - has it. I refer to this add-on daily. Thank you Quotidian!!

Very useful app to manage multiple library accounts. Has helped me save a lot of money.

Amazing....has increased my use of the library!!

This is a fantastic and extremely useful extension! Highly recommended.

Once added to FF and configured for your library (or libraries), the results automatically appear whenever you're browsing a book on a popular book site, like Amazon, GoodReads, and KoboBooks.

And, as a Canadian, it's great to see all our libraries included too!

This is a FANTASTIC extension! When browsing Amazon books, this just shows up on the page, and tells me if the book is available at in my local public library systems- I can click through to my library, put a hold on it at my nearby branch, and get an e-mail from the library when it's ready to pick up. Voila! And it's FREE- great for books you want to read, but not necessarily buy. This, and bookfinder.com, and you'll be in (real) book heaven.

This is wonderful!

This extension is incredibly helpful for big readers like myself! It consolidates all of my reading sites-- Goodreads, my local library, and Amazon kindle prices-- all in one place. Hugely helpful, definitely recommend!

Does exactly what it ways it will do. I am more impressed by how quick the developer responded to adding a library. When I first installed and went through the setup process I could not find my library listed. They have where you can request a library and have you enter the addresses for inline catalog and ebook catalog. I was expecting this to take weeks or months to get updated but they had my library added the very next day.

I love this! You can easily see if your library has the books you are looking for (and they often do!) Borrow things you'll only read once --and discover what else you library offers!

saves infinite kindle monies

This app has saved me hundreds of dollars in book purchases! I can look up interesting books in the eBook site and this app automatically tells me if the book is available at my local library. I pay for the library in my taxes. It only makes sense to use it

Now that I have Library Extension, I'm not sure I can function without it. It works great and saves me tons of dough on books.
I'd love to see Carnegie Library and state university library catalogs among those available in the extension, but Idk if those are available publicly in the way that the currently included library catalogs are, so it may not be possible (yet) to include them. Other than that tiny nitpick, this is a fantastic extension and I highly recommend it.

I love it. and don't worry publishers & authors (except Macmillan imprints, which I'm boycotting bc of the company's library policy): I often still buy the book even when my library has a copy - before, I would often put of deciding to buy until I checked library holdings, and then I'd forget to come back to purchase. This way I have that data immediately.
