My most indispensable extension after my adblocker. Quotidian's Library Extension checks library collections and allows you to choose *which* library collections to check (main aka the physical collection? or electronic collection? both?) and then they provide a link for found items. If you have just one library membership this app is a must - and if you have multiple, well, I don't know how you live without it.

One of my few mandatory extensions on every machine.

Really powerful and effective! Very clever idea and implementation.

Fantastic Time Saver!

I regularly use multiple libraries (city, county, other city, other county, university) and this extension is a time-saver AND a money-saver. Instead of searching five different library catalogs, I just end up on Amazon (which is where the internet wants me to go anyway 🙄) and the extension shows me what's available at all of my libraries. It's fantastic.

This extension has saved me $ and time each time I can borrow from the library instead of paying. I have to add that I still pay for some ebooks so I can continue to support Bookbub and my regular ebook discounters.

I use it all the time to track which books are available in the libraries I use. Indispensable.

This app has saved me so much time and money by showing me where I can find books to borrow versus buy. Tech support is very fast and Andrew is very responsive to my issues. Up-dates occur quickly in response to changes made by libraries, etc.

Very well done and useful for checking a book's availability by format in various libraries, all in one place. Developer was very responsive and kept me in the loop while fixing an issue after a recent update.

Extremely useful add-on! I was very surprised at how quickly a dev fixed it and responded when I sent a message about a library catalog not working.

This is such a helpful application!

Great little widget, had an issue and emailed the developer, who fixed it within 30 minutes!

Genuinely life-changing, I used to spend so much time checking my various libraries and hoopla to see if a book was available, and now it's just displayed for me automatically!

Very helpful and a great idea!

I literally tell everyone who I think could get some use out of this extension. Hoping it comes to mobile soon!
