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.

A great addition...when it works. Sometimes it shows multi-library service such as Colorado's Prospector as having nothing available, but when I check further it is available. But overall, this is a super service...sorry, Amazon!

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.

Useful extension. Although the "Internet archive open library" link more times than not, even thought it says there's a copy, there isn't.

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.
