This is NOT correct. It is highly dependent on the subject matter and what is filtered from Wikipedia before doing the comparison. Take a hard science and take everything that is written and Wikipedia is substantially worse. http://www.theregister.co.uk/2005/12/16/wikipedia_britannica_science_comparison/ http://www.theregister.co.uk/2005/12/16/wikipedia_britannica... Furthermore, take Wikipedia and compare it with authoritative books on the subject matter in the actual articles and you will find that Wikipedia contains many very serious errors. http://www.economist.com/node/17902943?story_id=17902943&CFID=159910163&CFTOKEN=53366793 http://www.economist.com/node/17902943?story_id=17902943&#38... (Search for Ofqual in that article.) In particular, Wikipedia is about as accurate as general books and press articles. It is not an accurate source of academic information.
