The open encyclopaedia, Wikipedia, is facing renewed criticism from media professionals and academics worldwide, who argue that it cannot be trusted as a credible source of information. Wikipedia is the largest encyclopaedia in the world, with over 3.7 million articles in over 200 languages. It has over 850 000 articles in its English version alone, more than four times as many as the next-biggest English encyclopaedia - Encyclopaedia Britannica. The issue at stake for many though, is how many of these articles are reasonably accurate and adequate.
