Upvoted. That's exactly the problem, and the way to solve it. Example: two months before the movie "The Social Network" got released to theaters in 2010 Facebook decided to add a robots.txt to Facebook.com. Immediately Archive.org deleted/disabled access to the archive how Facebook startpage looked in 2004-2010. BTW. the correct way would be to activate archive access to Facebook.com for the 2004-2010 time-frame again. The "The Accidental Billionaires: The Founding of Facebook" book and the "The Social Network" film based on that book used of course partly Archive.org and various other research methods to get the facts.
