You’re in luck.  There is a Web Archive site that periodically saves information from all sorts of websites around the world, and they’ve been doing it for almost 20 years.

You can use the above site to see what a website looked like long ago, and even get information form a website that’s been taken down.  Give it a try!

Note: most pictures are not saved, so it’s mainly good for researching text.
