The National Library of Finland is the foremost research library in Finland. Administratively the library is part of the University of Helsinki. The National Library is responsible for storing the Finnish cultural heritage. By Finnish law, the National Library is a legal deposit library and receives copies of all printed matter, as well as audiovisual materials excepting films, produced in Finland or for distribution in Finland. These copies are then distributed by the Library to its own national collection and to reserve collections of five other university libraries. Also, the National Library has the obligation to collect and preserve materials published on the Internet.
