Jules’s point that Wikipedia is a good place to start is spot on. But, as Jules notes, it needs to be just a start; avoid the temptation to end there. It’s true that the volunteers make corrections all the time. But sometimes in their zeal to be “correct” their personal views take over. The most notable example is how often people go into the Wikipedia reference for Nelson Mandela and “correct” the fact that he’s not a “black” but rather he’s an “African American.” Not sure he’d agree with that characterization!

This example is why many high schools and universities still do not allow Wikipedia as a valid reference. So students start with Wikipedia, taking ‘”leads” from there to more reliable sources to get data they can reference.
