This new implementation of URN:NBN resolver replaces the previous resolver running under this domain. The most significant change is the default behaviour: instead of redirecting directly to the resource, in case of error all registered links for the requested URN will be listed. For more information please visit the Homepage of the German National Library
Besides resolving the german and swiss URN subdomains, this resolver supports redirecting URN subdomains AT, CZ, FI, HU, IT, NL, NO, SE and the PI-Systems DOI® (doi:...), Handle (hdl:...), ARK (ark:...).
