In 2010, Twitter and the United States Library of Congress partnered together to archive every tweet by American citizens.

The story behind the answer

True. In 2010, Twitter agreed to donate its complete archive of public tweets to the U.S. Library of Congress, which viewed tweets as valuable historical records—much like letters, newspapers, or pamphlets. The aim was to preserve the digital public conversation for future research and understanding of culture, politics, disasters, and social movements.

Because of privacy, scale, and technical challenges, access to the archive was tightly restricted, and in 2017 the Library stopped comprehensive collection and shifted to selective archiving of significant events. Memory tip: think of tweets as modern “pamphlets”—brief, widely shared messages that capture the pulse of an era, saved by the nation’s library for historians of the future.
