Finna is part of the National Digital Library (NDL) project of the Ministry of Education and Culture.
The National Library of Finland bears the main responsibility for developing and maintaining Finna, but the actual development work is carried out together with Finna partners. The archives, libraries and museums involved in Finna are responsible for its content.
Finna's catalogue data are freely available, but statutory or contractual restrictions may apply to the digital images and back cover texts displayed in Finna, as well as to the digital content and metadata linked to in Finna.
The open interface of the finna.fi service at api.finna.fi brings the metadata produced by participating libraries, archives and museums to the public.
