The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed as the pre-inauguration crawl for part of the End of Term Web Archive, a collaborative project that aims to preserve the U.S. federal government web presence at each change of administration. Content includes publicly-accessible government websites hosted on .gov, .mil, and relevant non-.gov domains, as well as government social media materials. The web archiving was performed in the Fall and Winter of 2016 to capture websites prior to the January 20, 2017 inauguration. For more information, see http://eotarchive.cdlib.org/.
