Corrections

Every article that was revised after its first publication, newest revision first. The address and the first publication date never change; the page shows the update date.

No article has needed a revision yet.

How corrections work

A factual error, an outdated rule or a misleading wording is corrected in the article itself; the page then shows the date of the revision and appears in this list. Withdrawn articles stay at their address with a notice. To report an error, write to the editors.
