Corrections

Corrections should identify the page and, where possible, the observed issue. Published corrections are noted on the page rather than made quietly. For a published framework covering accuracy and corrections, consult the Editors’ Code of Practice.

Disagreement

Substantive disagreements should identify the claim being challenged and include supporting evidence.

Any commercial interest connected to a submitted claim should be disclosed.
