50 million registered URNs
|
We are pleased to announce that there are now over 50 million URNs, an impressive number, registered within the last 20 years together with our URN partners.
The Uniform Resource Name (URN) is a Persistent Identifier (PI or PID) that, unlike URLs, can be used to uniquely and consistently identify online resources regardless of where they are stored. URNs are available free of charge and ensure the long-term availability of online resources. The German National Library provides the URN-Service for Germany and Switzerland and has been managing and assigning URNs belonging to the namespace "urn:nbn:de" for 20 years.
Along with the shift of publishing into the digital world, the need for a supporting infrastructure has grown tremendously, and Persistent Identifiers such as URNs have become an integral part of science and research. That is why we continue to rely on our well-established URN infrastructure and will keep providing our expertise.
