Information that moves

Any detail that moves - figures, rules, and product details - should be checked against a current primary source, because a page written earlier can fall behind.

Updates and availability

The site is not guaranteed to be available at all times. Content may be revised or withdrawn at the operator's discretion.

Where outbound links go

Whoever runs that service sets the terms that apply there.

Amendments

Where this needs updating, the revised text replaces the old as soon as it appears here.
