Koha is a web based, fully featured, library management system. Originally developed by Katipo for the Horowhenua Library Trust in New Zealand, the first system went live in 2000. There are now many systems in operation in many languages on every continent.
The Koha Community (a global community of libraries of varying types and sizes, volunteers, and support companies) now develops Koha collectively and provides two major releases a year and maintenance releases every month.
There are 90 libraries using Koha in Ireland, across all types of libraries from schools to corporate and academic. Most Koha sites are hosted in Data Centres although Koha can also be implemented on-premises.
