Find the evidence. Manage the relationship.
Start with a record, then choose coverage. Existing subscribers can sign in independently of a new checkout.
Editorial update: . This is not a source-observation date.
Before choosing coverage
Filter the tracker by state, city or project. Open a record, inspect its official citation and check which observation details are missing. A source observation is not purchase intent.
Your account
Sign-in uses a one-time email link. Checkout is tied to the verified account; a return URL does not activate paid access. Billing status, scope and delivery preferences come from the server.
If a link expired or was already used, request a new one. If mail is unavailable, no direct sign-in token is displayed. Service outages are shown as errors, not as a new anonymous account.
Corrections and data requests
Use the private account support form for a source correction, service question or billing case. Keep the event identifier and citation when available. Your account also provides export and deletion-request controls subject to identity and retention checks.
