The U.S. Presidency may be an historic office, with great continuity across centuries, but the official White House website, WhiteHouse.gov, is very personalized.
In the span of a few moments, around 12:00 noon on 20 January 2017, the Whitehouse.gov site went from looking like this
to the “new” White House site.
Most, if not all, of the content in the White House site from the Barack Obama administration has been removed. In effect, the Presidential website is starting over. The Washington Post published a same-day article on the site transition.
Fear not — much of the content is preserved, one way or another, in an array of forms and repositories. For more information, see this University Library U.S. Presidents: Sites and Documents guide.
If you have questions (or suggestions), please contact Senior Reference Librarian Dick Grefe.
