Hello Chris , According to librarytechnology website which is not official from koha there are about 4,976 libraries declared to be using koha. https://librarytechnology.org/libraries/search.pl?ILS=Koha However libraries that allowed koha community to share their statistics are less than that in https://hea.koha-community.org/ you will find that total libraries only 1,767 And using koha dashboard you can get an idea about recent active developers : https://dashboard.koha-community.org/ using :https://hea.koha-community.org/ you can find more statistics about koha usage here you can find some historical timeline : https://koha-community.org/about/history/

- September 6 1999 Work starts on Koha - July 21 2000 Koha 1.00 put up for download

I hope that helps , Best regards On Fri, Aug 10, 2018 at 2:19 PM Chris Brown <chris@stayawake.co.uk> wrote:

Hello,

I have agreed to give a webinar on Koha to a group of community-managed libraries here in the UK. It would be interesting to include some basic facts and figures:

* How long has Koha been in existence? * How many libraries around the world are using it? * How many active developers are there?

Does anyone have estimates for any of these?

Thanks!
