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.

Works perfectly, a great extension!

This a wonderful and useful extension! Will save you a lot of money if you are a bookworm like me.

It works, but it erases the set up information when the browser closes. So I have to set it up over and over. The competing add on "Available Reads" keeps the information between restarts, so I don't know why this one doesn't.

One of the most useful extensions ever! Simple, accurate - and I use it on 3 libraries in my city.

Great extension, works as advertised. Very helpful to see library availability while browsing for books.

Library Extension is great. Performs as advertised... easily and quickly exposing if a book is available in my local library (Philadelphia Free Library... yeah!).

Incredibly useful with my local library, and also with Overdrive. Helps me avoid the tax-avoiding monopoly that is Amazon.

I used to do the library lookup separately. This app has saved me many hours of searching my library database to see if the books are there. And it also allows me to go directly to my library and put the book on hold. Amazing!
