The details
Governmental organizations publish debates, proceedings, reports, budgets, commissions, inquiries, audits, scientific findings, and other content. They spend billions of dollars annually on research.
But the reports are hard to find and often disappear. Coherent locates them, adds them to World Governments, makes backup copies, and assigns persistent identifiers—so that these historically important documents remain available.
