Presidents Links
https://www.archives.gov/presidential-libraries/archived-websites are Presidential records. The official files that make up a Presidential administration's website are preserved in our Executive Office of the President Electronic Records Archive. In order for the public to easily access the websites, the National Archives has taken an additional step to "freeze" the White House websites and make them available online. Because the archived websites are hosted by the National Archives and are historical material, they are no longer updated. Any broken links (internal or external) will not be updated.

This changed when the 20th amendment to the Constitution was adopted in 1933. Beginning in 1934, the convening date for Congress became January 3 (unless Congress by law appoints a different day), and beginning in 1937 the starting date for the presidential term became January 20. Because of this change, the number of Congresses overlapping with a presidential term increased from two to three, although the third only overlaps by a few weeks."
