Sometimes we want to see how a page has changed over time, or know when a page disappeared. Using the Wayback Machine can help you do that.<\/p>\n

Here's how that works. Go to the Wayback Machine<\/a> and search for a page or site. Here we'll search for the front page of the White House site:<\/p>\n

\"\"<\/p>\n

The Wayback Machine doesn't archive every page, but they do archive an awful lot of them. Whether a page is archived will often depend if a page was heavily linked to in the past, or if it was published by a site that the Wayback Machine tracks. In the case of the White House, of course, both these things are true and we have a near perfect history of the site.<\/p>\n

\"\"<\/p>\n

Let's go back in time all the way to 1999. When we select 1999, we see a calendar. Each circle indicates a snapshot made of the site. The green and blue indicate whether the page was a \"redirect\" -- an issue beyond the scope of this article.<\/p>\n

Click on a date to see a \"snapshot\" of the page on that date. Here we see a snapshot of the site from January 1999, at the tail end of the Clinton administration.<\/p>\n

\"\"<\/p>\n

Sites will be browsable, to some extent, so go ahead and click on the links. Advanced functionality, such as search interfaces and interactive content will usually not work.<\/p>\n
