US Library of Congress to archive Twitter

Every tweet since 2006 will be archived.

The US Library of Congress, home to the Declaration of Independence, will archive every tweet since 2006.

The news itself came in less than 140 characters: "Library to acquire ENTIRE Twitter archive - ALL public tweets, ever, since March 2006! Details to follow."

The decision is an ambitious one, as the micro-blogging site has 150 million users, and continues to tack on another 300,000 every day.

A post on the Library's Facebook page said: "So if you think the Library of Congress is 'just books,' think of this: The Library has been collecting materials from the web since it began harvesting congressional and presidential campaign websites in 2000. Today we hold more than 167 terabytes of web-based information, including legal blogs, websites of candidates for national office, and websites of Members of Congress."

"In other words, if you want a place where important historical information in digital form should be preserved for the long haul, we're it!"
