Koha is the first open-source Integrated Library System (ILS). In use worldwide, its development is steered by a growing community of libraries collaborating to achieve their technology goals. Koha's impressive feature set continues to evolve and expand to meet the needs of its user base.
Full-featured ILS. In use worldwide in libraries of all sizes, Koha is a true enterprise-class ILS with comprehensive functionality including basic or advanced options. Koha includes modules for circulation, cataloging, acquisitions, serials, reserves, patron management, branch relationships, and more. For a comprehensive overview of features visit the Koha feature map.
Dual Database Design. Koha uses a dual database design that utilizes the strengths of the two major industry-standard database types (text-based and RDBMS). This design feature ensures that Koha is scalable enough to meet the transaction load of any library, no matter what the size.
Library Standards Compliant. Koha is built using library standards and protocols that ensure interoperability between Koha and other systems and technologies, while supporting existing workflows and tools.
Free / Open Source. Koha is distributed under the open-source General Public License (GPL). More information on the GPL can be found here.
No Vendor Lock-in. It is an important part of the open-source promise that there is no vendor lock-in: libraries are free to install and use Koha themselves if the have the in-house expertise or to purchase support or development services from the best available source.
