Methodology and Source Rules
How the atlas labels sources, preserves uncertainty, and handles public records and historical captures.
Method in brief
- Start with a primary regulation, dataset, university record, or direct archive capture.
- Record the source family and retrieval context.
- Keep reported values separate from derived values.
- Leave a gap visible rather than filling it with an estimate.
- Preserve historical paths and redirect unresolved families to the closest relevant archive page.
Why this belongs in the atlas
The atlas is designed to be legible to a reader who wants to follow the evidence. The methodology page explains this process, and the contact address offers a route to flag a correction or a useful source.
For source details and known limits, consult the references in the rail. The first release is intentionally useful at a modest scale: it establishes a dependable route through the public record and leaves room for verified additions.
