Recent addition of Scribd catalog is very appreciated!

I wrote in about my library database changing, expecting a fix to take weeks. It was fixed in literally seven minutes. 6/5 stars :)

Very helpful. I have cards for 2 library systems with OverDrive and Hoopla and this shows me from the book page on Goodreads if a library owns the book, the format(s), and what is available to check out from library or Hoopla.

Amazingly helpful. Makes searching for new books so much easier when I only have to view one site. I'll look up the book on goodreads to see if I'm interested and then check if the book is in my library all on the same page.

This extension is always there showing me which libraries have the book I'm looking at, and it's amazing! It has links taking me directly to the book at my library so I can check it out right away.

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!
