LOCKSS
Open Journal Systems supports the LOCKSS (Lots of Copies Keep Stuff Safe) system to ensure a secure and permanent archive of journals. LOCKSS is open source software developed at the Stanford University Library that allows libraries to preserve selected web journals by regularly polling registered journal websites for newly published content and their archives. Each archive is continuously validated against other library caches, and if content is found to be corrupt or missing, another cache or journal is used to recover it.
