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

Very useful, Subscribe to a paid site, but can see if a public library that I have a card for has it available. Saved me more than a few credits.

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.
