Archiving Policy

This journal utilizes the PKP Preservation Network (PKP PN) to create a distributed digital archive, ensuring permanent access to all published content even if this journal's website should become unavailable in the future. The PKP PN is a free preservation service developed by the Public Knowledge Project, built on LOCKSS technology, and provides automatic, ongoing archiving of the journal's retrospective and future content across multiple independent preservation nodes.

This journal has also enabled infrastructure supporting the LOCKSS (Lots of Copies Keep Stuff Safe) and CLOCKSS (Controlled Lots of Copies Keep Stuff Safe) systems, allowing participating libraries to create additional permanent archives of the journal's content for purposes of preservation and restoration.

LOCKSS is open-source software developed at Stanford University Library that enables libraries to preserve selected web journals by regularly polling registered journal websites for newly published content and archiving it. Each archive is continually validated against other library caches, and if the content is found to be corrupted or lost, the other caches or the journal is used to restore it.
CLOCKSS is based upon the open-source LOCKSS software developed at Stanford University Library, using the same polling and validation mechanism to preserve web journals against loss or corruption.
