An unclassified document from the National Security Agency from 2007 has some nice words to say about the Internet Archive, Brewster Kahle, and the Wayback Machine.

“The Wayback Machine is, very simply, one of the greatest deep web tools ever created.” -National Security Agency (2007)

The Internet Archive & the Wayback Machine

You have to give Brewster Kahle credit for thinking big. The founder of the Internet Archive has a clear, if not easy, mission: to make all human knowledge universally accessible. And, who knows, he might just succeed. What has made Kahle’s dream seem possible is extremely inexpensive storage technology. As of now, the Internet Archive houses “approximately 1 petabyte of data and is currently growing at a rate of 20 terabytes per month. This eclipses the amount of text contained in the world’s largest libraries, including the Library of Congress. If you tried to place the entire contents of the archive onto floppy disks (we don’t recommend this!) and laid them end to end, it would stretch from New York, past Los Angeles, and halfway to Hawaii.” 102 In December 2006 the Archive announced it had indexed over 85 billion “web objects” and that its database contained over 1.5 petabytes of information. 103

But that’s not all that Kahle and company have archived. The Archive also now contains about 2 million audio works; over 10,000 music concerts; thousands of “moving images,” including 300 feature films; its own and links to others’ digitized texts, including printable and downloadable books; and 3 million hours of television shows (enough to satisfy even the most sedulous couch potato!). Kahle’s long term dream includes scanning and digitizing the entire Library of Congress collection of about 28 million books (something that is technically within reach), but there are UNCLASSIFIED some nasty impediments such as copyrights and, of course, money. None of this deters Kahle, whose commitment to the preservation of the digital artifacts of our time drives the Internet Archive. As Kahle puts it, “If you don’t have access to the past, you live in a very Orwellian world.”
