Koha is an Integrated Library System with a range of features including: 

• Online Public Access Catalogue (OPAC) module which provides a simple and clear interface for library users to perform tasks such as searching for and reserving items and suggesting new items.

• Full catalogue module which enables library staff to capture details of all library items. 

• Circulation module which fully automates borrowing and item management, integrating with the OPAC so users can see which items they have outstanding, for example.
