Remember, Wikipedia articles can be a good starting point, but you should also be sure to use other, more scholarly sources of information as well. Please use Wikipedia responsibly and wisely!

Because of the collabortive nature of Wikipedia, and that changes can be made by anyone in real time, Wikipedia articles develop at different paces and are, therefore, not created equal. The quality of Wikipedia articles range from excellent to very poor and this page will give you tips for evaluating a Wikipedia article's quality.
