About the National Library of Finland
● The National Library of Finland is the oldest and largest scholarly library in Finland. Our origins date back to 1640, when the Academy of Turku was founded.
● We are responsible for the collection, description, preservation and accessibility of Finnish printed national heritage and the unique collections under its care.
● We provide the Finnish Thesaurus and Ontology Service Finto, a platform for publishing controlled vocabularies, implemented using Skosmos software.
