web erasure and the memory hole

In recent weeks, I've followed the story in the Times of the quiet controversy over the White House's decision to place robot.txt files on their website preventing any pages mentioning the administrations policies in Iraq from being archived by Google or the Internet Archive. It seems this administration would prefer to keep the Web from serving as any kind of historical memory with regard to its policies in Iraq, and would prefer that its website not interfere with its own approach to the malleable past. I followed a link from the Times today to the memory hole, a site that grabs, scans, and makes public many documents about which publishers had second thoughts. Some, such as the DoD's September 23 Draft Board Notice are fairly ominous.
