Tracking Government Data & Access

The End of Term Web Archive captures and saves U.S. Government websites at the end of presidential administrations. The EOT has thus far preserved websites from administration changes in 2008, 2012, 2016, and 2020.

Access historical versions of U.S. government websites from before January 20, 2025 with a simple URL change. How it works: Take any .gov URL and add wayback.com right after .gov, and you'll be redirected to the Wayback Machine's archived version of the page.

In January 2025, the White House website was archived as a way to preserve the online presence of the administration of President Joseph R. Biden Jr. The official files that make up a Presidential administration's website are preserved in the National Archives’ 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 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 Because the archived websites are hosted by the National Archives and are historical material, they are no longer updated.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.

A project of the Harvard Law School Library Innovation Lab, this is a regularly updated mirror of Data.gov, the US federal government data finding and storage site. Note that this process "runs a 'shallow crawl' that collects only the directly linked files. Datasets that link only to a landing page will need to be collected separately."
