Remember that study published in the journal Nature about how Wikipedia is only slightly less accurate than the Encyclopedia Britannica when it comes to certain articles about science? Apparently, it made the folks at Britannica nervous enough to look into the study itself. They sent around an e-mail to a select group today encouraging people to read their refute of that research.
3/28: Nature responds (.pdf) to Britannica’s assertions, mentioning that Britannica contacted Nature soon after the study appeared, but Britannica did not follow up with Nature’s initial response. Nature explains more about the process of completing their study and demonstrates that they tried to treat Britannica and Wikipedia the same.
