The journal uses the LOCKSS and CLOCKSS systems to create a distributed archiving system among participating libraries and allows those libraries to create permanent archives of the journal for preservation and recovery purposes. All content in the CLOCKSS Archive and the Global LOCKSS Network is maintained with explicit publisher permission, secured through written contracts or through online permission statements. We work closely with the implementers of the LOCKSS network to facilitate the development of governance and legal requirements appropriate to the content, jurisdictions, rights, and access capabilities involved.
