The Federal Register is the official daily journal of the documents published by the federal agencies of the U.S. government.
The Freedom of Information Act (FOIA) "provides that any person has a right, enforceable in court, to obtain access to federal agency records, except to the extent that such records (or portions of them) are protected from public disclosure by one of nine exemptions or by one of three special law enforcement record exclusions."
