I met a traveller from an antique landWho said:—Two vast and trunkless legs of stoneStand in the desert. Near them on the sand,Half sunk, a shatter'd visage lies, whose frownAnd wrinkled lip and sneer of cold commandTell that its sculptor well those passions readWhich yet survive, stamp'd on these lifeless things,The hand that mock'd them and the heart that fed.And on the pedestal these words appear:"My name is Ozymandias, king of kings:Look on my works, ye mighty, and despair!"Nothing beside remains: round the decayOf that colossal wreck, boundless and bare,The lone and level sands stretch far away. 1818 P.B. Shelley

Digital PreservationSystematic management of digital works over an indefinite period of time Processes and activities that ensure the
continued access to works in digital formats Requires ongoing attention--constant input of
resources: effort, time, money

Backups ≠ Digital Preservation
Backups are tactical measuresMake copies to restore originals after data loss event. Typically stored in a single location • Often nearby• Collocated with the servers backed up
Backups address short-term data loss with minimal investment resources

Digital Preservation is Strategic
Long-term, error-free storage and for the entire time span the information is required.Realistically address issues in preserving information over time
Ongoing investmentGeographically dispersed set of secure caches Multi-institutional collaboration
DDPN: Distributed Digital Preservation Network
![Page 6: Collaborative Preservation of ETDs: The MetaArchive Cooperative and LOCKSS](https://reader035.fdocuments.us/reader035/viewer/2022062222/568163cb550346895dd5087d/html5/thumbnails/6.jpg)
Distributed Digital Preservation NetworkSecure
PLN: Private LOCKSS NetworkReduces the likelihood that any single cache will be compromised
Distributed GeographicallyReduces likelihood that loss of any single cache will lead to loss of the preserved information.A single organization is unlikely to have the capability to operate several geographically dispersed and securely maintained servers.Inter-institutional agreements will ensure commitment to act in concert over time.
