The page ships derived transcription data, not scans. Every source and the terms used for this
page are listed below.

The manifest's licence_url is retained for schema compatibility and applies only to W1 and W2.
The per-witness rights statuses and metadata URLs are in record.json under record.witness_rights;
the three records with no rights field are kept explicitly unknown.
