How do I create a subdomain?
If you are not a registered user of the PURL resolver on which you want to create a subdomain, you must become one. You are then able to create subdomains in domains of which you are a writer. To create a subdomain explicitly, point your Web browser to a PURL resolver, for example, OCLC’s PURL resolver, and follow the resolver’s instructions for creating a subdomain. The PURL resolver should tell you immediately whether or not your subdomain was created successfully. To create a subdomain implicitly, create a PURL which has a nonexistent subdomain in its name. If you are a writer of the last existing domain in the PURL’s name, then the subsequent nonexistent subdomains will be created automatically during the creation of the full PURL name you requested.
