Wikipedia as Accurate as Britannica?

Not as accurate, but certainly close, as Nature writes. The growing online phenomenon that is Wikipedia has nearly 4 million entries, with information on everything from world leaders to Pokemon. The site isn't without problems though, as anyone can edit entries, which has lead to some recent problems with the site's credibility. Still, the collection of information Wikipedia has to offer, and the lack of a price tag for the service, has made it a favorite research spot for millions of curios people.

"The exercise revealed numerous errors in both encyclopaedias, but among 42 entries tested, the difference in accuracy was not particularly great: the average science entry in Wikipedia contained around four inaccuracies; Britannica, about three."
