DuckDuckGo bangs are great for this. Just add !wayback (with the space) after the URL of the article you are reading, and it will search the Wayback Machine for that article.
Example: If the URL for the article is website.com/propaganda.html, change it to website.com/propaganda.html !wayback and press enter.
