"This is a nice little tool. Simply whack in the URL of the page that you're interested in, and it will come back with a list of other pages out there which share a substantial amount of similar content. You can then highlight the offending page, see what it's copied and then go direct to the page to double check. I don't think it's quite as good as Copyscape, but it's worth looking at."
