History buffs dove into thousands of pages of government records released online this week, hoping for new nuggets about President John F. Kennedy’s assassination. They instead found revelations about U.S. espionage in the massive document dump that also exposed some previously redacted personal information.

New records about JFK’s assassination shed little new light on the killing. But they revealed the names of CIA assets whose spycraft had been a secret even to family members.
