Links are never hidden behind a paywall of ours. Where a copy of the page exists it is linked beside the source with the date it was taken, because news links rot and a dead link next to a saved copy is still evidence. Some copies predate this register: they were made by the Internet Archive before we existed, and the date shown is the date of that copy, not of our visit.
