Library of Congress to house Twitter data

Patrick Hoge

The Library of Congress will house Twitter Inc.'s archives of the billions of tweets that users broadcast on its micro-messaging platform, the company said Wednesday, the first day of its "Chirp" developer conference at the Palace of Fine Arts Theatre in San Francisco.

Twitter co-founder Biz Stone said in a company blog post that the Library of Congress, which collects copies of books, pamphlets, maps, prints, and sheet music registered in the United States, had "signaled to us that the public tweets we have all been creating over the years are important and worthy of preservation."

Only after a six-month delay can the Tweets be used for internal library use, non-commercial research or public display by the library itself, Stone wrote.

Also Wednesday, among many other announcements, Twitter disclosed that it has 105.7 million registered users and that it is collecting 300,000 new accounts a day, 60 percent of them non U.S. Users issue fifty-five million tweets a day.

The San Francisco company, which has raised about $155 million since 2006, has 175 employees, up from 65 in July.
