description: The National Bibliography Number (NBN), is a URN-based publication identifier
  system employed by a variety of national libraries such as those of Germany, the
  Netherlands and Switzerland.  They are used to identify documents archived in national
  libraries, in their native format or language, and are typically used for documents
  which do not have a publisher-assigned identifier.
