What is Koha?
Koha is a full-featured open-source ILS. Developed initially in New Zealand by Katipo Communications Ltd and first deployed in January of 2000 for Horowhenua Library Trust, it is currently maintained by a team of software providers and library technology staff from around the globe.
I have been a Koha developer since 2005, when I became a full time employee of the Crawford County Federated Library System, and the Meadville Public Library. Since that time, I have contributed a number of features and bug fixes to the project, as well as creating the Koha Offline Circulation utility, and creating the Koha Virtual Appliance.
