Studies indicate that the information on Wikipedia is, in fact, accurate.  The only systematic comparison of Wikipedia’s quality against its leading traditional rival, the Encyclopaedia Britannica, showed Wikipedia to be of similar accuracy. A survey in the leading journal Nature compared 42 pairs of articles on a wide range of science subjects. [1] Experts in each topic found that Wikipedia’s user-contributed articles had only 30% more errors and omissions overall than Britannica, despite the latter’s much vaunted pride in its expert authors and editors. And as Wikipedia is a constant work-in-progress, these faults were quickly corrected, whereas a traditional publication like Britannica will only revise articles at intervals of years, if not decades, if they ever do. So, over time, errors in traditional encyclopaedias persist longer than in Wikipedia.  [1] Giles, J. (2005, December 15). Special Report: Internet encyclopaedias go head to head.
