Investigation, not intake

Search → recognize → discover → deepen

  1. 1Describe the real world

    Business, address, intersection, incident, or condition—in your own words.

  2. 2Confirm the place

    Use the normalized place and map context to make sure it is right.

  3. 3Explore the history

    Read attributed records chronologically and distinguish fact from possible connection.

  4. 4Check another layer

    Ask for documents, alternate names, additional agencies, or similar records.

Statewide entry, transparent coverage

Start with California. Narrow only when the data requires it.

The search accepts any California place. Live municipal-source coverage currently includes San Francisco, Los Angeles, Sacramento, Oakland, and Long Beach; available record categories vary by city. Coverage gaps are shown as limitations, never as proof that nothing happened.
