Methods
Use Sanborn Maps for Neighborhood Context
This field note is part of the FOBA learning stream. It is meant to orient readers and point toward better source work.
Key points
- A Sanborn sheet can show what surrounded an address: churches, schools, stores, rail lines, industrial sites, halls, and street changes.
- The map supports neighborhood context, not a person-specific claim by itself.
- The safest map note names the sheet, date, symbols, and exact context claim being made.
Next steps
- Capture city, volume, sheet, date, address, building use, symbols, and nearby institutions.
- Compare the map with directories, deeds, tax records, newspapers, churches, schools, and cemetery records.
- Do not use a map alone to prove residence, ownership, identity, ancestry, legal status, descent, or membership.
