Follow the White Rabbit

Article Checker checks websites and articles for plagiarism. Copy and paste a block of text in the text box, select the search engine you want to use (google or yahoo) and then click on compare. I copied and pasted a paragraph from a wikipedia article and within seconds I was given a list of websites where the text could be found. It seems that the wikipedia article was plagiarized by a number of sites. You can also upload a text file (not .doc but .txt) and Article Checker will scan the text.
