Where can I check the preprint policy of the journal?

Authors can verify a journal's preprint policy directly through publisher platforms or specialized databases. Such policies detail permissible sharing of unreviewed manuscripts prior to submission. Key sources for locating preprint policies include the specific journal's website, usually within sections titled "Instructions for Authors," "Author Guidelines," or "Editorial Policies." The comprehensive SHERPA/RoMEO aggregator is the primary independent database indexing publisher and journal self-archiving policies globally. Additionally, publisher-level policy statements often provide overarching guidelines applicable to their journals. Always confirm at the individual journal level, as policies vary considerably across publishers and between subscription and open access titles. Understanding a journal's specific preprint rules before submission is essential to avoid potential conflicts. Researchers should primarily check the journal website and cross-reference with SHERPA/RoMEO to determine crucial details: whether preprint sharing is permitted, if specific licenses (e.g., CC BY) apply, version restrictions (e.g., submitted vs. accepted manuscript), and platforms where posting is allowed. This practice ensures adherence to journal guidelines and supports responsible sharing of preliminary findings.
