Identify the version and its status
Label the work accurately as a preprint, accepted manuscript or version of record. A preprint is not evidence that the article has completed journal peer review. If several versions exist, explain the relationship and direct readers to the current record.
Check permissions before choosing a repository
Review permitted versions, timing, licence and any embargo. Institutional or subject repositories may have their own deposit requirements. Open access does not always mean an author fee, and paying a fee does not eliminate every restriction on third-party material.
Keep research materials usable
For permitted data or code, include a description, version, licence and instructions sufficient to understand the files. Do not expose participant identifiers, restricted information or material you do not have permission to share. An access statement should accurately describe any restrictions.
Link and maintain the record
Connect the shared version to the journal publication when available. Update records after corrections and avoid leaving readers with an unexplained superseded version. Confirm the target journal’s policy before submitting material previously shared as a preprint.
