Corrections and source revisions

Inspect retained source changes and report an evidence-backed correction.

Source revisions and editorial corrections have distinct meanings. A source updating a statement does not by itself establish a new appearance. Stable source-item identities preserve the original publication date, revisions and occurrence evidence.

How to report a correction

Use the correction link on a record or the contact form. Include the record ID, source URL, the field that needs correction and supporting primary evidence. Accepted requests are stored privately; delivery and review remain pending until confirmed. No response time or editorial review is claimed without a recorded outcome.
