The Center for Research Libraries has certified Portico as a trustworthy digital repository.
Here's an excerpt from the announcement:
This month the Center for Research Libraries (CRL) announced the completion of an audit of the Portico digital repository and its certification as a trustworthy digital repository. Portico is the first digital preservation service to undergo this independent audit and the only service to be certified at this time.. . .
The nine-month audit process was an extremely positive and valuable one for Portico. It confirmed that the majority of our practices conform to the Trustworthy Repositories Audit and Certification Checklist (TRAC) and other metrics developed by CRL through its analyses of digital repositories. It also identified for us several areas for continued improvement as well as ways in which we can enhance the service for CRL member libraries as well as others. We look forward to continuing to report to CRL on these issues in the years ahead to ensure we continue to meet certification requirements and the expectations of CRL libraries, our other partner libraries, and our participating publishers.
We invite you to review the background information about CRL's Certification and Assessment of Digital Repositories Program (http://www.crl.edu/archiving-preservation/digital-archives/certification-and-assessment-digital-repositories) as well as the public audit report on Portico published by the CRL Certification Advisory Panel (http://www.crl.edu/archiving-preservation/digital-archives/certification-and-assessment-digital-repositories/portico).
