Koha is a web-based integrated library system capable of managing a wide range of administrative processes typically found in modern libraries: cataloguing, authority management, serials management, circulation, acquisitions, reporting, etc.

​

Via its online catalogue (OPAC), it is possible to promote the library’s collections and simultaneously provide a set of services to its readers without them having to physically commute to the library. Such services include loan renewals, reservations, submitting acquisition suggestions, etc.

​

Koha is compatible with various international library standards, such as, MARC21, UNIMARC, MARCXML, ISO 2709, Z39.50, SRU/SRW, SIP2, RSS, etc.

​

This software is implemented in thousands of libraries around the world, from small personal libraries with a few hundred items to large university libraries holding millions of items.

• 1. No licensing costs
  Koha is an open-source software. This means that there are no licensing costs associated with it.
  Koha runs on top of an open-source operating system and uses an open-source database management system, which also materializes in a reduction of costs at the infrastructure level.

• 2. Compatible with any platform
  Koha is a 100% Web-based solution. To use the system, you only need a browser. The software is centralized on a server, and there is no need to install applications on users’ workstations.

• Access to the system can be done from anywhere and from any device, desktop or tablet.

• 3. Configurable according to the needs of your library
  This solution is highly configurable. It allows circulation rules to be defined according to the policy of your institution, the attributes associated to each user profile can be adjusted, item types, collections and design of patron cards can be configured to meet the requirements of your institution.
  It is also possible to set up the graphical user interfaces to meet the branding identity of the client institution.

4. Support for library networks
A single Koha instance can support a network of libraries. Each of these libraries can operate independently and according to their own internal policies.

In addition to an effective reduction of costs, this enables a centralised view of the information and management processes.
Performance indicators can be extracted for all the libraries simultaneously, and the cataloguing process can be coordinated centrally.

5. A library closer to its users
Readers, in addition to being able to search the library catalogue online, can place reservations and renew their current loans.

Furthermore, they can export, print, and save records, view their search history and loan history, consult fines, change personal information, manage reading preferences, create document lists, among other operations.

The software provides a set of services that take the library closer to its readers, extending it beyond its physical space.

6. Interoperability is key
Koha implements interoperability protocols such as OAI-PMH and Z39.50, enabling the import of records from other information systems.

The system also supports the import and export of bibliographic records and users in various formats such as ISO 2709 and MARC XML.

These features facilitate the interoperability of information with other library management systems, as well as the reuse of existing information and a perfect exit strategy in case of succession.
