Source hierarchy
We prefer original records, institutional catalogs, official surveys and nominations, peer-reviewed scholarship, and documented oral histories. Tourism pages and community references can identify leads but do not replace the underlying evidence.
Clear status
Staff-managed records identify a source and review state. Estimates, approximate map points, interpretive composites, family traditions, and unresolved identifications should be labeled rather than presented as settled fact.
Inclusive interpretation
Coal and rail history includes workers, families, labor, migration, race, gender, health, environment, community life, and change—not only companies, technology, prominent owners, or nostalgic stories.
