Perhaps it was in celebration of National Library Week that the Library of Congress, the mother of all libraries announced that they’d be archiving all the tweets tweeted since Twitter’s creation in 2006.

According to a memo released yesterday, Twitter has donated its digital archive of public tweets to the Library of Congress.

In case you haven’t been paying attention, Twitter now has 105 million registered users and is adding 300,000 new ones every day. That’s a lot of tweets to archive, but if anyone is up to the task, it is the LOC, who just recently held a workshop helping others archive their digital media.

Since 2000, the Library has been collecting materials from the web since it began harvesting congressional and presidential campaign websites. Today the Library holds more than 167 terabytes of web-based information, including legal blogs, websites of candidates for national office and websites of Members of Congress.

The Twitter archive will include the first-ever tweet from Twitter co-founder Jack Dorsey, President Obama's tweet about winning the election, as well as millions of others notable tweets.
