When you need to see an older version of a website, this is possible by using the Wayback Machine from Internet Archive.  You can browse through over 150 billion web pages archived from 1996 to a few months ago. This resource can be very helpful when a newer version of a site no longer has a piece of information you are looking for or if you are just curious about what a site used to look like!

To start surfing the Wayback, type in the web address of a site or page where you would like to start, and press enter. Then select from the archived dates available. The resulting pages point to other archived pages at as close a date as possible. Please note at this time, keyword searching is not currently supported.
