Meet the Activist Archivists Saving the Internet from the Digital Dustbin
A web site you looked at some time ago may have since been deleted. If you want information from that now-unavailable web page, did you know that you might be able to find the information from an online archive?
An article by Mark Hill has been published on the Discover Magazine web site that describes the Internet Archive and its subsidiary, the Wayback Machine. It also describes how to use them.
You might want to read the article now. In addition, I would suggest you bookmark that page so that you can find it in the future anytime you have a need to retrieve data from a no-longer-available web page.
NOTE: As explained in the article, not all web pages are archived forever. However, millions of pages have already been archived and many more are being added every day.
