Records of the United States Government - 17 USC 105, and this is the one source where that citation genuinely applies (it does NOT reach territorial material). NARA also states rights per record in useRestriction/accessRestriction and those are carried into the catalogue per document. 'Restricted - Possibly' and 'Undetermined' are NARA CATALOGUING PLACEHOLDERS meaning unadjudicated, not prohibitions - NARA serves those files publicly, and refusing them cost the Truman Library's ten-part Hastie interview on the first run.
