LETS: Journal of Linguistics and English Teaching Studies utilizes the PKP Preservation Network (PKP PN) to electronically safeguard and maintain access to its journal content. You can find more information on this in the Publisher Manifest.
The PKP has introduced the PKP Preservation Network (PKP PN) as a means to digitally conserve OJS journals. The LOCKSS program, which forms part of this network, offers a decentralized and distributed preservation system, ensuring uninterrupted and perpetual access while preserving the original, authentic content. The PKP PN is especially valuable for journals not included in other digital preservation services like CLOCKSS or Portico, as it secures their long-term accessibility. For further insights into the PKP PN, please refer to the high-level overview (an initial discussion document).
