Errors in the Encyclopædia Britannica that have been corrected in Wikipedia

And let's not forget that recent article in the Chronicle of Higher Education where Wikipedians were obstinately refusing to allow an authority on the subject to fix some errors in an article on the Haymarket Affair, or even to take his input on how the article should be fixed.

Their official position on the subject was, as I remember, to point out that Wikipedia articles aren't meant to represent the facts; they're meant to represent popular conceptions. (Perhaps that's why their articles on health topics tend to be so bad about parroting pseudoscientific hogwash?)

I know, it's impressive.

I am sure I, like many people, have found dozens of errors in Wikipedia. I used to try to correct them, but gave up when my changes would get reverted, even with references.
