The Declassification Engine by Matthew Connelly

What History Reveals About America's Top Secrets

The book chronicles a research and engineering effort to digitize and machine-read millions of U.S. government records to reveal patterns and consequences of state secrecy, showing how classification expanded across administrations, hid mistakes, and shaped policy; through case studies and data-driven analysis it demonstrates how secrecy often undermines democracy and proposes reforms—such as time-based automatic declassification, stronger oversight, improved archival practices, and penalties for overclassification—to make government information more accountable and accessible.
