Koha Suomi consortium (Finnish academic libraries)
When Ex Libris's Voyager system — reliant on costly Oracle databases and described as ageing and unmaintained — reached the end of the road, Finnish academic libraries split over what should replace it. A large group, including the University of Jyväskylä, moved to a shared, open-source Koha platform (the Koha Suomi consortium), with support anchored by the National Library of Finland. The projected savings ran into the millions of euros over a decade — and rather than exporting that money to multinational vendors, the state redirected it into local technical jobs maintaining the open-source infrastructure. A flagship national-scale example of open-source library migration.
