This document discusses authority records in Koha, including what they are, how to import or create them, and system preferences that affect how they are handled. Authority records are standardized forms of names, subjects, and other information used to control access points in a catalog. They can be imported, created manually or automatically by Koha. Preferences determine if authorities are automatically generated during cataloging and whether new ones can be created. Authorities are linked to bibliographic records to connect access points, and this linking can be done during cataloging or in batch processes.
