Portico

Portico (www.portico.org) is a not-for-profit digital preservation service providing a permanent archive of electronic journals, books, and other scholarly content. Portico is a part of ITHAKA (www.ithaka.org), a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. As of October 2009, the Portico archive preserved over 14 million e-journal articles and 1,900 e-books. Portico worked with CRL in 2006 on a test of the RLG/NARA Draft Audit Checklist for the Certification of Trustworthy Digital Repositories and other metrics developed by CRL under a grant from the Andrew W. Mellon Foundation.

CENTER FOR RESEARCH LIBRARIES

The Center for Research Libraries (CRL - www.crl.edu) 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 has a hybrid strategy of preserving and maintaining shared physical collections of materials and certifying digital repositories of interest to its community.

CRL analysis of Portico documentation and operations was undertaken by Marie Waltz and Bernard Reilly. Additional technical support for the site visit and assessment was provided by James A. Jacobs, Data Services Librarian Emeritus, University of California, San Diego.

To guide its Portico audit, CRL formed a panel of advisors representing the various sectors of its membership. The Certification Advisory Panel is constituted so as to ensure that the certification process addresses the interests of the entire CRL community. The Panel includes leaders in collection development, preservation, library administration, and digital information technology. The members of the CRL Certification Advisory Panel are:
