Wikipedia is the most accurate encyclopedia to date; its perceived unreliability as to its correctness is largely a misunderstanding that arose from misconceptions as to why one can’t (or shouldn’t, depending on case) cite it in academia. People think that it can’t be cited because of its unreliability but in reality it’s simply because it’s a third hand source; i.e. a resource.

Wikipedia is built near-purely on second hand sources, which is how all encyclopedias are intended to be constructed. As long as one ensures the validity of the second hand source used, encyclopedias are great resources.
