'Pedia vs. 'Paedia

Nature has just posted the first peer-review-based comparison of the science coverage of the Wikipedia and the Encyclopaedia Britannica. (I thought that last link was entertainingly ironic. How 'bout you?) Nature had experts in various fields examine 42 articles in each encyclopedia for errors. (The reason they chose 42 articles is, of course, obvious.) The numbers of inaccuracies in the two texts were similar: about 4 per article in the 'Pedia and about 3 per article in the Britannica. For more info on which articles were compared and how the two reference texts came out, check out the Nature study.
