Chronopolis Audit Report 2012

Chronopolis: About the Audit Participants


At the time of the audit Chronopolis ( comprised four partner organizations that provide digital preservation services: the San Diego Supercomputer Center, the University of California San Diego Libraries, the National Center for Atmospheric Research, and the University of Maryland Institute for Advanced Computer Studies. Originally funded by the Library of Congress National Digital Information Infrastructure Preservation Program (NDIIPP), Chronopolis now depends upon the expertise and resources of the four partners to provide a geographically distributed, heterogeneous and highly redundant archive system. 

At the time of the audit Chronopolis managed three geographically distributed copies of four collections from within the NDIIPP community: the extensive archive of public opinion data of the Inter-university Consortium for Political and Social Research; and diverse sets of data files from the California Digital Library, North Carolina Geospatial Data Archiving Project, and the Scripps Institution of Oceanography. 

Center for Research Libraries

The Center for Research Libraries (CRL - is an international consortium of university, college, and independent research libraries. CRL supports advanced research and learning in the humanities, sciences, and social sciences by ensuring the survival and accessibility of source materials vital to those disciplines. In order to enable its community to accelerate the shift to electronic-only resources in a careful and responsible manner, CRL both preserves and maintains shared physical collections of materials and evaluates digital repositories of interest to its community.

CRL analysis of Chronopolis documentation and operations was undertaken by Marie Waltz and other CRL staff.  Additional technical support for the site visit and the assessment of Chronopolis repository systems and architecture was provided by Ann Green of Digital Life Cycle Research & Consulting.

To guide its Chronopolis audit CRL also enlisted a panel of advisors representing the various sectors of the academic research libraries field.  The Certification Advisory Panel included leaders in collection development, preservation, library administration, and digital information technology, and is so constituted as to ensure that the certification process addresses the interests of the entire CRL community.
