Does the journal allow me to submit an updated version of an existing article?

Many journals permit submitting updated versions of an existing manuscript, although policies vary significantly and adherence to specific guidelines is mandatory. Submission rules depend on the journal's editorial policy, distinguishing between updating preprints prior to acceptance and revising already published articles. Permissible updates typically require substantive improvement, such as correcting critical errors or adding significant new results. Transparent disclosure of the article's version history and prior submission status is essential. Authors must meticulously consult the specific target journal's "Instructions for Authors" concerning versions and preprints to ensure compliance. This capability facilitates manuscript improvement before peer review or after posting preprints, allowing authors to refine content and address preliminary feedback. To implement: verify the journal's explicit policy on versions/preprints within its guidelines; prepare the revised document; upon submission, clearly indicate any prior versions (e.g., preprint server details) and thoroughly document all substantive changes in a cover letter explaining the rationale. Proper execution enhances scholarly communication and manuscript quality while maintaining academic integrity.
