IES: Journal of Islamic Elementary School Journal has electronic backup and preservation access to its journal content through the PKP Preservation Network (PKP PN). This can be seen in the Publisher Manifest.

PKP has developed the PKP Conservation Network (PKP PN) to preserve OJS journals digitally. The LOCKSS program offers decentralized and distributed preservation, unlimited perpetual access, and preservation of the original original version of the content. PN PKP ensures journals that are not part of other digital preservation services (such as CLOCKSS or Portico) can be preserved for long-term access. For additional details on PKP PN, please see the high-level overview (initial discussion document).
