Britannica has announced that it will start to wikify its online content (though they don’t use that term/mock it and Wikipedia–“Wikipedia contributes to the spread of information and many people are happy with it as their only source of reference – as are many people happy to eat McDonalds every day.” ) to allow registered users to submit changes to Britannica article. The catch/way that this is different from Wikipedia?
a) Britannica will check on the accuracy of all changes/articles before changes can be viewed
b) You have to pay money to access the site and edit the site.
So while it might not be an economical investment for students or those who aren’t relying on accurate information to win a court case/prepare a brief/perform research, it might be worth looking into if you want guaranteed accurate content with an old-school brand name.
