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.

What this field note adds

  • It gives readers a shorter editorial waypoint between a raw research question and a fuller flagship or wiki treatment.
  • It makes one method, caution, or place-based reading move visible enough to reuse elsewhere on the site.
  • It keeps the project thinking in public instead of hiding every refinement until a large page rewrite happens.

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.

Reader use test

A useful field note should leave the reader with one clearer question, one better source path, and one safer wording choice. If it only leaves a broad conclusion, route the topic into a source table or claim review before reusing it.

How to use this field note

  • Treat it as a method prompt, not a final evidence packet.
  • Carry forward the question, caution, or source pathway rather than only the conclusion.
  • Open the relevant place hub, field guide, source-review page, or claim-review page before repeating stronger wording.
  • Submit a Community Note or Fact Check when the note exposes a missing source, contradiction, or wording risk.

Source trail

What remains open

A field note is a directional page, not a final proof packet. Readers should expect to continue into source tables, claim review, community notes, fact checks, or larger place-based articles before treating the topic as settled.
