Quotation records can change when better evidence appears.
How corrections to quotation wording, attribution, source identity, topic mapping and explanations are handled.
What can be corrected
Quotation wording, author labels, source titles, dates, attribution status, topic relationships, source notes and explanations can all be revised.
Conservative default
When an attribution becomes uncertain, the safer approach is to show that uncertainty rather than preserve a stronger claim.
Source changes
If a better edition, archive link or source locator becomes available, the source reference can be updated while keeping the quotation context clear.
