How to cite the ledger

What to include so a reader can check you, not just quote you.

Snapshot 2026-10-25 240 claims 138 citations 209 people

The ledger is designed to be quoted and checked. A citation that includes the snapshot date, the record id and the person's name is enough for anyone to find the same row and the same sources.

Quoting the ledger without the snapshot date is the most common error, and the one that makes a number unfalsifiable within a year.

FieldWhy it matters
Record idUnique and stable; finds the row
Snapshot datePins the numbers to a moment
Person and venuePrevents a claim being read as the dataset's own
VerdictStops a quote being mistaken for an endorsement
