Bibliographic identifiers function as names for objects that exist both in print and, increasingly, in electronic formats.
A registration request for acquiring a Namespace Identifier (NID) "NBN" for national bibliography numbers has been written by the National Library of Finland on the request of the Conference of Directors of National Libraries (CDNL) and the Conference of the European National Librarians (CENL). Chapter 5 contains a URN namespace registration request modeled according to the template in RFC 2611.
The document at hand is part of a global co-operation of the national libraries to foster identification of electronic documents in general and utilisation of URNs in particular. Some national libraries, including the national libraries of Finland, Norway and Sweden, are already assigning NBN-based URNs for electronic resources.
