Digital preservation policy

EVSOS supports the LOCKSS (Lots of Copies Keep Stuff Safe) system which guarantees the journal a permanent and secure archive. LOCKSS is an open source programme developed by the Stanford University Library that allows libraries to preserve selected web journals by regularly searching registered journals to collect new published content and archive it. Each archive is continuously validated against records from other libraries, so any damaged or lost content can be restored using those records or the journal itself.

See the EVSOS LOCKSS Publication Manifesto page. Deposit to it is through the PKP Preservation Network (PKP PN), which deposits content using the LOCKSS Program, which offers decentralized and distributed preservation. This allows journals that are not part of any other digital preservation service (such as CLOCKSS or Portico) the ability to be preserved for long-term access.

Additionally, EVSOS uses persistent identifiers which can be found in our policies section and performs an incremental backup policy every 12 hours provided by Paideia Studio servers via JetBackup 5.
