Corrections policy
When something is wrong, we correct it clearly and use the mistake to improve the work around it.
How to report an issue
Send the article URL, the statement you believe is inaccurate and any supporting source through the contact page.
What happens next
We assess the evidence, contact relevant sources where useful and update material errors promptly. Significant corrections should be noted on the article; small spelling or formatting fixes may be made silently.
Product updates
A product changing, being discontinued or becoming unavailable is normally treated as an update rather than a correction. The updated date records meaningful editorial revisions.
