Archiving Policy

The PKP Preservation Network (PKP PN) provides Journal of the Nigerian Society of Physical Sciences with electronic backup and preservation access to the content of its journals. In the Publisher Manifest, this is shown.

For the purpose of digitizing OJS journals, PKP has created the PKP Preservation Network (PKP PN). The LOCKSS software provides seamless perpetual access, distributed and decentralized preservation, as well as the preservation of the content's true original version. The PKP PN makes sure that journals that are not included in any other digital preservation service (like CLOCKSS or Portico) may be saved for long-term access. Please kindly refer to the high-level overview (a preliminary discussion document) for further information on the PKP PN.
