Future Research Technology Platform for Professional Knowledge Management (Archive & Library - Family History & Genealogy) The Internet Archive Wayback Machine contains petabytes of data (1000 terabytes each), eclipsing the amount of text contained in the world's largest libraries, including the Library of Congress. The size of the world's total digital content exceeds 500 exabytes. According to IDC (International Data Corporation), noted in The Expanding Digital Universe (pdf), and annual current surveys, total amount of global data exceeds a zettabyte, as of 2010. "In 2006, the amount of digital information created, captured, and replicated was [estimated to be] . . . about 3 million times the information in all the books ever written. By 2007, the amount of information created surpassed the storage capacity available." "The use of paper in the world is still increasing (nearly 5% in the last five years). But we have clearly hit a threshold -- where the digital universe is now pervasive enough to be a major locale for commerce, education, social interaction, and entertainment."
