Encyclopaedia Britannica and Nature: a response
In our issue of 15 December 2005 we published a news article that compared the
Internet offerings of Encyclopaedia Britannica and Wikipedia on
scientific topics
("Internet encyclopaedias go head to head", Nature 438 (7070) p900-901).
Encyclopaedia Britannica has now posted a lengthy response to this
article on its
website, accusing Nature of misrepresentation, sloppiness and indifference to
scholarly standards, and calling on us to retract our article. We reject those
accusations, and are confident our comparison was fair.
