I wrote my own version of something like this, but this is more powerful and more polished. Use it every day

This is the kind of extension (and application of browser technology) that deserves much more attention. Such things need to help us with our daily lives and interactions with people. Computing should support social interaction, and libraries are some of our most important spaces to interact today. Bravo! We need more work like this.

Saves me time several times a week. One of the best extensions ever. Really. Right up there with URL shorteners and ad blockers. Invaluable.

It just works. What a great extension. It's saved me tons of time and money, and I'm supporting my local library more often to boot! Love the concept, love the execution.

This extension is great, I love that I don't have to open 3 different windows to check if a book is available.

I use a lot of local public libraries and I buy a lot of books. This helps me decide which avenue to pursue. Thank you so much - keep up the good work. I hope you will be able to make it work in Firefox also.
