I've recently noticed a lot of self-published books on Amazon that just pull their text straight from Wikipedia articles, like this (http://www.amazon.co.uk/Articles-Nintendo-Including-Pictochat-Connection/dp/124253895X/ http://www.amazon.co.uk/Articles-Nintendo-Including-Pictocha...) or this (http://www.amazon.co.uk/Articles-Nintendo-Including-Pictochat-Connection/dp/124253895X/ http://www.amazon.co.uk/Articles-Nintendo-Including-Pictocha...). Most of them have little disclaimers that presumably get them past Amazon's rules but they're still cluttering up a lot of search results and doubtless tricking a few people.
