At least one past president burned his papers.

(AMHERST, MASS.) Prior to 1978, U.S. presidents could do what they pleased with the records from their time in office. They owned them.

But in 1978, the Presidential Records Act established new rules for the official records of a president. Passed in the wake of Watergate, when President Richard Nixon tried to keep incriminating materials from being made public, the law changed who legally owned the papers: It was now the American public.
