Keep calm and MARC on - Koha in the K10plus galaxy

K10plus is Germany's largest union catalogue with over 1000 academic and research libraries participating and containing over 90 million bibliographic records. K10plus provides central cataloguing, metadata and infrastructure services. Koha is increasingly adopted as an ILS by many K10plus libraries.
The presentation discusses the approaches used to connect Koha to K10plus, including bibliographic data workflows, synchronization mechanisms, and the use of standard interfaces to ensure smooth interaction between Koha and the shared cataloguing infrastructure. It aims to contribute practical insights for libraries considering Koha in a cooperative cataloguing environment like K10plus.
