The U.S. Library of Congress says it will no longer collect every single tweet published on Twitter as it has been doing for the past 12 years. 

The library said this week that it can no longer collect everything across the entire social media platform because of recent changes Twitter has made, including allowing longer tweets, photos and videos. 

It said in a blog post this week that its first objective with collecting and archiving tweets was “to document the emergence of online social media for future generations.” The library says it has fulfilled that objective and no longer needs to be a “comprehensive” collector of tweets. 

The Library of Congress said it will still collect and archive tweets in the future, but will do so on a more selective basis. It said going forward “the tweets collected and archived will be thematic and event-based, including events such as elections, or themes of ongoing national interest, e.g. public policy.”

The library said it generally does not collect media comprehensively, but said it made an exception for public tweets when the social media platform was first developed. 

The library said it will keep its previous archive of tweets from 2006-2017 to help people understand the rise of social media and to offer insight into the public mood during that time. “Throughout its history, the Library has seized opportunities to collect snapshots of unique moments in human history and preserve them for future generations,” it said.

“The Twitter Archive may prove to be one of this generation’s most significant legacies to future generations. Future generations will learn much about this rich period in our history, the information flows, and social and political forces that help define the current generation,” it said.
