Wikipedia accurate as Britannica--AP circa Dec 15

...is about as accurate in covering scientific topics as Encyclopedia Britannica, the journal Nature wrote...[using] peer review....Based on 42 articles reviewed by experts

Of eight "serious errors" the reviewers found--including misinterpretations of important concepts, four came from each source....

...the free service...having the speed and breadth to keep up on topics....not covered in Britannica




It turns out that Nature may itself have been a very naughty mag on this survey. It's certainly got Britannica rather cross:
