> the recording and definition of "errors"

Well, I can imagine. Many of the 'errors' in Britannica are those related to the fact that it is not up to date I suppose. For Britannica these are, of course, not errors - the entries are just dated. They are only wrong (and thus 'errors') to anyone who wants to use the thing as a reference that is abreast of developments. This is where wiki is 'more right';-)
