How can I confirm whether my article has undergone peer review by the journal?

To confirm peer review status, examine journal documentation and your submission correspondence. Several clear indicators exist regarding whether an article underwent peer review. Firstly, check the journal's official website for its stated peer review policy; reputable scholarly journals explicitly declare this practice. Secondly, inspect communications received during the submission process, particularly the editorial decision letter, which typically details reviewer comments and feedback. Thirdly, access your manuscript record in the journal's online submission system; it often contains logs of review invitations, reviewer reports, and revisions. Be aware that not all manuscript types (e.g., editorials, letters) undergo peer review, even in peer-reviewed journals. Finally, contact the journal editor directly if records remain unclear. Practically, log into the manuscript submission portal to locate review history or decision letters. Verify this information against the published article; acknowledgment sections sometimes thank reviewers. Confirming peer review is vital for establishing scholarly credibility, demonstrating rigorous evaluation, and ensuring compliance with institutional or funder requirements regarding dissemination.
