A preprint can be defined as a version of a scholarly paper that precedes formal peer review and publication in a peer-reviewed scholarly journal. KJM allows authors to submit the preprint to the journal. It is not treated as duplicate submission or duplicate publication. KJM recommend authors to disclose it with DOI in the letter to the editor during the submission process. Otherwise, it may be screened from the plagiarism check program — Similarity Check (Crosscheck).
Preprint submission will be processed through the same peer-review process with a usual submission. If the preprint is accepted for publication, authors are recommended to update the info at the preprint with a link to the published article in KJM, including DOI at KJM. It is strongly recommended that authors cite the article in KJM instead of the preprint.
