THE EVIDENCE BEHIND THE MAP

A catalog with a memory.

71,344 typed entities and 256,742 source-reported assertions.

Systems, service points, and locations retain separate identities. Every assertion links to a source record and reporting period. FY2024 records do not establish current operation.

What is modeled

History and relocations; collections and services; access and library cards; official websites and crawls; favicon provenance; conflicts and identity decisions; cited narratives and model-run records.

What is populated

The national survey baseline is populated. Website verification, individual library favicons, histories, and generated narratives remain not researched. Defining these fields does not mean we have collected those facts.
