Beware when researching of simply Googling "War of 1812" or even using Wikipedia as a source. Many sites that a Google search will link you to may turn out not to be credible and may even give you incorrect information. Most professors will not allow you to cite Wikipedia in a paper. However, Wikipedia is a good launching point if you use it to look for sources and references at the bottom of the page. You should still check any of these sites for authenticity by checking who their sources are. If you're uncertain about any website, check with your professor before using it as a source. If in doubt, don't use it.
