Once the Center's teams digitize a manuscript, the process of preserving their work for the future begins. The massive quantity of data requires an extensive system that is secure and in conformity with archival standards set by the National Archives and Records Administration and the National Archives of the United Kingdom.
CSNTM digitizes in RAW and then converts every image to uncompressed 16-bit TIFF and JPEG formats. The collaborating institutions receive copies of their images in the formats that meet their needs.
"Dr. Wallace and his team displayed at all times the utmost care and respect for these irreplaceable texts and I can personally attest to their professionalism, the quality of their work, and their willingness to share all data with the host institution."
- Dr. Brendan Haug, University of Michigan
Expandable remote access servers allow CSNTM to continually add new images to its archive and maintain the database from anywhere in the world. This server is backed up with a RAID 6 protocol that rewrites all the data in multiple locations. Additionally, the Center uses LTO-6 tape cartridges to save each RAW and TIFF file for long term storage. These tapes preserve the images for decades while holding large quantities of data. Finally, the data are stored in multiple locations in order to provide a complete disaster-recovery plan.
According to the copyright standards for each institution, the Center makes images available for viewing in its digital library.
