JDTREA provides electronic backup and preserves access to all content in the event that the journal is no longer published by archiving all material in the National Library of Korea (https://www.nl.go.kr/). In accordance with the self-archiving deposit policy of Sherpa/Romeo (http://www.sherpa.ac.uk/), authors cannot archive pre-print (i.e., pre-refereeing); however, they can archive post-print (i.e., final draft post-refereeing). Authors can also archive the publisher’s PDF-file version.
