The reader’s problem
A date can look precise while being wrong.
What changed
The October correction work addressed source records with inconsistent publication and signing dates, year mistakes or placeholders. It added a date-correction table so a changed value could be inspected together with its explanation and supporting evidence.
Using the feature
For research that depends on chronology, compare the original date, the correction and the Gazette information. Keep the correction record with your extract. This makes it possible to explain why a library date differs from the source catalogue rather than silently overwriting the discrepancy in a spreadsheet.
Reading the evidence
A correction is not a guarantee that every date in the collection has been checked. Some records remain uncertain or lack enough evidence to settle a value. Distinguish a documented correction from an inferred date, and check the original publication when timing has legal consequences.
