The PKP Preservation Network (PKP PN) was created by PKP to digitally archive OJS journals. The LOCKSS program offers decentralized and distributed preservation, seamless perpetual access, and preservation of an authentic original version of the content. The PKP PN ensures that journals that are not part of any other digital preservation service (such as Portico) can be preserved for long-term access.
