The most important site for webpublishers

Copyscape

Copyscape dot com

Just type in the URL of your articles and it finds out if any other site is stealing your content!

The first search I did revealed TWO articles which had been copied by a college club website.

This is definitely a site to bookmark...

Brilliant site
One problem though - it's addictive!
Had to drag myself off it.

Found one of my main pages copied exactly also used my pictures as well.
Thanks for the great tip

I found a few false positives, and a lot of scraper directory listings. It seems quite effective, but no more so than putting some of your unique text into Google, because it seems like that's what they are using to check for infringement.
