The Corpus

Every federal regulation. Every state statute. Every municipal code in America. 13.125 billion court records, and every bill across all fifty state legislative sessions and the federal session.

Beside the law sits the record it produced: public finance, health, environment, labor, energy, education, transportation, agriculture, disclosures, and state operational data.
