This extension is my most used and is amazing. It has all the super niche libraries too and if anything needs any tweaking (rarely) the support is immediate and correct.

Hajrah·2 Sept 2026

This extension is great - it has all my local libraries. Support is even better: my local library changed something and stopped working - I emailed support and within an hour the library catalog URL was updated and the extension is working again. Give it a try!

Brent·9 May 2026

I've been using the Library extension plugin for a few years now, and it's great. They were even able to quickly get my local library's URL updated when I emailed them that it had changed earlier this year.
