Imagine you read a story on a news website which included details about someone. You send the link to your friend who reads it a day or two later. In the meantime the details have been completely changed and there's no proof the article said what you definitely read it said. How would you go about reading the original words?
I've tried a Chrome extension and that hasn't helped. WayBack Archive only has it from the day after you sent it. How else can you read it? In the good old days I feel I could looked at cached content from the date it was first cached by clicking on the dots on Google next to the link. But I can't see how to do it anymore.
