When one needs to do research on a certain topic or is just curios, one usually wikipedias it. Wikipedia has become a go to source – one can find out enough on a certain subject to be knowledgeable. Unfortunately Wikipedia is not that reliable in terms of using it as a source for a paper. Wikipedia has a few mistakes on its articles but overall it gives you a good idea on the subject. I personally use Wikipedia to find articles and books for a research paper. Wikipedia is a good starting point.
