Koha is an open-source integrated library system that was first developed in New Zealand in 1999-2000. It provides core library functions such as cataloging, circulation, serials management and more through a web-based interface. Koha is free to download and use, can be customized to any language, and has a large global user community for support. For these reasons, the document recommends Koha as a cost-effective alternative to proprietary library software for Pakistani libraries.
