About a year ago, OCLC completed a two-year project (funded by the Andrew W. Mellon Foundation) with the Center for Research Libraries (CRL) that, among other enhancements, added support for the registration of serial retention commitments in WorldCat. These enhancements not only help improve discovery of shared print data (PDF) across all OCLC services, but also bolster CRL’s Print Archives Preservation Registry (PAPR) and other partner efforts.
At the time that project was completed, we estimated OCLC and its member institutions would register about 15 million commitments over the course of the year. As of today, the community has actually added more than 25 million retention commitments.
