FedFlix was a joint venture with the National Technical Information Service (NTIS). Each month they send us government videotapes. We upload them to the Internet Archive and YouTube, then send the government back their videotapes and a digital copy for their files. No cost to them, more data for all of us. Enjoy!
One can also subscribe via RSS feed to government documents such are Congressional hearings, congressional bills, presidential papers, federal register, house journal, and others.
