# Institutional Evidence Graph
An institutional evidence graph links claims and identities to records maintained by courts, government agencies, insurers, educational institutions, scientific repositories, registries, and other authoritative sources.
## Notebook evidence
[[Scanned_20260730-1845]] preserves Delta Dental and Lakeshore Technical College records (PDF page 39), Delta travel/lost-item records (pages 40–41), legal and company-formation portals (pages 63 and 65–66), and PACER, CDC Stacks, EFMA, and Massey photometry (page 67).
## Analytical role
The cluster shows a move from searching the open web toward locating the institution that owns or publishes the primary record. The institutions have different authority scopes: a court docket, insurance eligibility record, corporate registry, public-health repository, and scientific dataset are not interchangeable.
## Boundary
Finding a portal or repository does not prove that a particular record exists there, that it is accurate, or that the notebook owner accessed it.
