What is a URN (Uniform Resource Name)?

A URN (Uniform Resource Name) is an identifier that facilitates the unique identification and citation of the associated online publication in the long term regardless of where it is stored. We provide a URN service which indexes the registered URN and establishes links to the locations (URL) of the online publications whenever queries are sent through the URN resolver.

URN are systematically assigned to all online publications archived by the German National Library.

More information is available from our URN service.
