Public Papers of Presidents are generally papers or statements issued by the White House or the White House Office of the Press Secretary, as well as speeches given by the President. Some volumes also contain correspondence between the President and other figures of the time if it has been entered into the record, but correspondence is generally kept separate.
Much of the presidential public papers are now available online due to either expired copyright or being produced more recently when these documents began to be considered public property. Please see the below list and links to the presidential public papers of your choice.
