Wikipedia corrects Encyclopedia Britannica
Those who have voiced skepticism over the reliability of information found in Wikipedia should take note of this.
The collaboratively assembled encyclopedia maintains a page devoted to correcting errors in its chief offline competitor, the venerable Encyclopedia Britannica.
This doesn't prove Wikipedia's superiority, of course, but it does underscore one crucial advantage: An online research tool can at least issue corrections after initial publication, in real time--even if they involve mistakes made by somebody else.
