Public and Private Record Sources

Where to find records — public registry indexes, local survey office records, private + agency sources.

The hook

Records research extends far beyond the county recorder. Private survey archives, neighbor recollections, utility-company records, historical aerials, oral histories — all may inform a boundary determination. Breadth of sources is the skill.
