Long Term Preservation

Long-term preservation of open-access journals is a process that publishers of academic writing must undertake. Acta Law Journal (ALJ) carries out a long-term digital archiving and preservation program.
Long-term preservation strategy protects against the termination of the publisher as a whole, a single journal, or a single back issue. This can be caused by business interruption or failure (bankruptcy, insolvency), catastrophic failure, technical failure, or natural disaster.


Acta Law Journal (ALJ) Publishing has decided to archive all journal documents with the PKP Preservation Network (PKP-PN). An archival service provided by the Public Knowledge Project to preserve Journals digitally using the Open Journal System Software. In short, PKP-PN offers decentralized and distributed preservation, seamless ongoing access, and preservation of authentic original versions of content.
PKP PN is a dark archive. End users will not have access to preserved content until after a “trigger event.” After a trigger event, PKP staff will approve the import of preserved content into one or more OJS instances hosted by PKP member institutions. Once uploaded to this OJS host instance, the content will be publicly accessible.


Content preserved in the PKP PN is only available to users after a trigger event, when it will be accessible to the reading public. The PKP PN defines two types of trigger events.


    1. Explicit notification by the OJS Journal Manager
    2. Termination of retention to the PKP PN (after a period of inactivity)


The PKP PN will use automated techniques to detect potential trigger events and contact journals to confirm their publication status.
