History & CultureHow it works
How to open a web page that has been deleted.
The Internet Archive has been collecting web pages since 1995 and has offered them as the Wayback Machine since October 2001 – now over a trillion captures. You enter the address at web.archive.org and pick a date from the calendar. "Save Page Now", available since October 2013, lets you capture a page yourself before it vanishes.
Useful: Archive any page you plan to cite at the very moment you cite it.
