The journal Sciences & technology A, exactes sciences relies on the services of the "PKP Preservation Network" project to ensure the long-term preservation and archiving of its content.
PKP has developed the PKP Preservation Network (PKP PN) to digitally preserve OJS journals. The LOCKSS program offers decentralized and distributed preservation, seamless perpetual access, and preservation of the authentic original version of the content. The PKP PN ensures that journals that are not part of any other digital preservation service (such as CLOCKSS or Portico) can be preserved for long-term access.
The PKP PN Network will deposit published journal content into PKP's private LOCKSS network for preservation.
Check the PKP-PN Official Site for more details about the PKP PN and how to use it.
