What is welcome
- Errors: a wrong input, unit, step, date, grade, quotation or attribution.
- Better sources: a first-hand record, measurement or study that should replace or sit beside the one cited.
- A second road: an independent way to reach an estimate, with its inputs and where they come from.
- Public-domain image leads: include the source page and the license or the basis for public-domain status.
- Corrections from institutions: changes to how an item in your collection is credited or described.
- Questions to work out: they need a named thing in them and at least one number that can be checked. No promise that any will be taken up.
What helps with an error report
Give the page address, the step or sentence, what you think it should say, and where that comes from. If the error is in a sum, the row of the Check my math table is enough to find it.
Confirmed errors are corrected at the foot of the page and on the Corrections page. A correction entry says whether it was reported by a reader, and it does not name you.
