Internet Archive
One of my all-time favorite internet tools is the Wayback Machine. This website provides access to an archive of webpages dating back to 1996. The goal of the site is to preserve digital data and currently, they store 2 petabytes of data. The next time you find a dead link, try copying the URL into the Wayback Machine, you will often find an archived version of the webpage you were trying to find. You can also use the Wayback Machine to look at old iterations of a current website. For example, searching for http://president.colostate.edu in the Wayback Machine will link you to the CSU President’s website from 2003, 2004, 2005.
