Documented implementation
Federation of Church Libraries FIDES — Central Catalogue
The Federation of Church Libraries FIDES documents that its Central Catalogue launched in 2014 using Koha; the current federation page says the catalogue is maintained by 32 member libraries. This is one shared federation catalogue, not 32 independently counted installations. Catalogue login or access restrictions are not evidence against the documented service.
