If possible, include primary source materials. Make a complete list of these materials, arranged according to a system of your choice, and include it with your paper when you turn it in. You may use any sources of information that are appropriate to your topic. You should try to find material both in books and in periodicals. Note that you must be very careful of information you find on the Internet.
Websites are convenient, but also of extremely uneven quality and difficult to evaluate.
If you include websites in your bibliographies, you must submit a completed evaluation form for each one of them with your bibliography. First, outline and summarize what the author of the text says about the topic. Second, summarize what you've learned about the topic from your research. Third, outline a position of your own on the topic , in response to the views you found in the text and in your research. Try to present your position so that anyone who reads your paper will find it reasonable, sensible, and plausible, and perhaps will feel inclined to share it with you.
