You can use NRS Web Admin to create a URN to an important web resource.
...
- Production: http://nrs.harvard.edu/urn-3:HUL:nrs-admin
- QA: httphttps://nrsnrsadmin-qa.lib.harvard.edu/urn-3:HUL:nrs-admin-qa
The Opening page of NRS Web Admin looks like this:
Click on the Create link next to the Search link:
Pick a Naming Authority from the drop down list. You should only see the Naming Authorities that you have permissions for:
After you pick a Naming Authority, you should see options for adding a Resource Name and a URL:
By default, the Resource Name will have '{n}', which creates a unique number. You can replace this default value or leave it. Enter the URL for your resource into the URL field.
After pressing "Create URN" you should see an Edit URN page for your new URN:
The
http://nrs-qa.lib.harvard.edu/URN-3:HUL.TEST:100001165
In the example below, the authority path HUL.OIS has been selected. 
If you do not know the appropriate authority path, contact your local NRS Administrator. Consult the NRS Status page to identify you local NRS Administrator.
In the example below, the new PID is urn-3:HUL.OIS:22414.
...
The 'Copy' icon next to the link in the FULL URN field will copy the entire URN, with the resolver URL, to your clipboard, so it can be pasted in another place.
This URL was copied using that Copy icon:
http://nrs-qa.lib.harvard.edu/

(If you are working with the QA/test version of the NRS Web Admin, use the NRS address http:// nrstest.harvard.edu/ instead.)
...
The Full URN should resolve to the URL you entered right away. (Though in some rare cases, it may not resolve until the next day.)
