RPD provides electronic archiving and preservation of access to the journal content in the event the journal is no longer published, by archiving in the National Library of Korea and ScienceCentral (https://www.e-sciencecentral.org/journals/182). According to the deposit policy (self-archiving policy) of Sherpa/Romeo (http://www.sherpa.ac.uk/), authors cannot archive pre-print (i.e., pre-refereeing) but they can archive post-print (i.e., final draft post-refereeing). Authors can archive the publisher’s version/PDF.
