The massive anti-war have produced no shortage of reports and comment on the internet.
A good place to start is www. punchdown.org which claims over 200 pictures from 133 global demonstrations, including over 40 cities in North America and one in Antarctica.
Many newspapers ran reports covering the demonstrations. The New York Times report of 17 February, available at www. nytimes.com (registration required) gives a US take on the London demonstration and the crisis facing Blair, commenting that in Europe 'the breadth and magnitude of the demonstrations opened a rift between ruler and the ruled, convincing many that street protest had overtaken conventional democracy in expressing the popular will'.
One of the great things about the internet is that you can access international newspapers and their archives, getting a global perspective on events. There are a number of websites that provide links to international newspapers--but try the Internet Public Library's list at www.ipl.org, which includes a good number of Middle Eastern English language papers.
For an alternative view on the protests, indymedia.org is good, and a socialist perspective can be found on the websites of Socialist Worker's sister organisations--find them through the IS Tendency's website at www. istendency.org
Many of those who attended the London protests never reached Hyde Park, or couldn't hear the speeches due to the huge numbers present. www.cableradio.co.uk provided a useful service with their live online coverage of the speeches made recordings of which can be found on their website.
George Bush and his planned war have spawned many spoof e-mails and humour sites. www.dubyaspeak.com gathers many of Bush's pearls of wisdom ('Bushisms' as they are becoming known) into one place to entertain and terrify you. According to the site, when asked by a reporter, 'Given the size of the protests in England over the weekend, do you have any concerns that Tony Blair might pay a serious political price for supporting you on Iraq?' Dubya answered, 'First of all, you know, size of protest, it's like deciding, well, I'm going to decide policy based upon a focus group.'
