I didn't expect to use this extension but I have quite often. It works great.

This extension is the most useful, saving me from having to search our public libraries when looking at a book online, and in any format. Highly recommended.

I love this extension. I've never left a review for an extension before, but I had to for this one: it's super useful, unobtrusive, and does precisely what it claims to do, and no more.

I love this extension, use it very often, and have recommended it to several friends. I wish the option to save/import/export configuration was more prominent in the settings menu as only just discovered it today. It would have made installing the extension across several computers a lot less tedious!

Easy to use and an excellent complement to libby. Found via Cory Doctorow's blog at pluralistic.net. adversarial interoperability at its finest!

This extension is probably the most useful one I have, aside from an ad-blocker. It is so easy to add my libraries, and it saves a ton of time instead of searching in each catalog. Highly recommend!

Magnificent add-on. Wish I'd have found it sooner.

Absolutely brilliant stuff, and unthinkably convenient for something I'd never stopped to consider the possibility of. Earnestly recommending this to everyone I speak to from now on.

Super-useful integration with OverDrive to save money.

Makes everything much more streamline when trying to find books!

I love it so much, but I wish there was a feature for when a book isn't available in your library to send a message asking if they can add it to their collection.

I have 10 or so different library cards, and Library Extension is so incredibly helpful. I love being able to see at a glance whether a certain book is available from any of my libraries, or how long the wait will be. Favorite extension ever.

Saves a lot of time searching library catalogues! Very quick to respond to issues, too.

This add-on is so convenient. I love being able to set the libraries I want to search and have that search performed automatically.
