How it works

We review and update every article weekly. When the record changes, so does the article.

The weekly cycle

• Monday: re-check. Every published case goes through a scan of its sources and of new reporting. Each case shows the date it was last checked and when the next check is due.
• When the record changes, the case gets a dated entry in its update log, with its own sources. Earlier text isn't quietly rewritten. Corrections are labeled as corrections.
• When nothing changes, only the last-checked date moves. Quiet isn't the same as closed.

Sources

Cases are original rewrites of public records from around the world: archives, newspapers, official reports and peer-reviewed papers. Each one is linked so you can check it yourself. More on sourcing, images and status labels is in How we work.

Following along

Every dated update across the site is collected on Watch, with an RSS feed. Spot something wrong? See the corrections policy.
