Recently we recommended that OCLC declare OCLC Control Numbers (OCN) as dedicated to the public domain. We wanted to make it clear to the community of users that they could share and use the number for any purpose and without any restrictions. Making that declaration would be consistent with our application of an open license for our own releases of data for re-use and would end the needless elimination of the number from bibliographic datasets that are at the foundation of the library and community interactions. I’m pleased to say that this recommendation got unanimous support and my colleague Richard Wallis spoke about this declaration during his linked data session during the recent IFLA conference. The declaration now appears on the WCRR web page and from the page describing OCNs and their use.

While libraries pay substantial fees to OCLC and other providers for services including deduplication, discovery, and enhancement, they do not do so with the intent that their records should then be siloed or restricted from re-use. Regardless of who has contributed to descriptive records, individual records are generally not copyrightable, nor is it in the public interest for their use to be restricted.
