Version 2.0.0 (build #162), released October 10, 2026, includes 39,171 selected U.S. publisher and printing-service locations. Usage supplies the location base. Publication adds published contacts and classifications. Master adds reported brand relationships, alternate names, and matched historical context.

Use location_id to join child tables to a selected location. Contact, classification, and brand-link totals count related rows, not separate businesses. Joining multiple child tables directly may multiply results. The September 23, 2026 source snapshot is not a live operating-status or deliverability guarantee. Published contact fields do not grant marketing consent.
