The National Repository Library (NRL) is a resource shared by all Finnish libraries and information service centres. The NRL is the most economic way of storing library material. Because of the NRL, the need for extra shelf space in libraries throughout the country is decreased and can be controlled.
The basic function of the NRL is to receive, store and offer material for the use of other libraries. The NRL serves university and special libraries as well as public libraries, and acts as a connecting link in the library network.
