Library of Congress has announced that it will create a digital archive for all public tweets published since March 2006.  The average number of daily tweets is 50 million.  According to the Library of Congress: “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.”  Several questions arise from the perspective of information management:  How will these tweets be archived to ensure long-term preservation and access; what search mechanisms will be put in place to help people search through terabytes of data; how will it enable searching in multilingual platforms, given the universal nature of Twitter?
