You should strive for presenting an argument that is clear, concise, and logical. References to source material should be made using endnotes numbered sequentially. The endnotes containing your references should appear after the main text. The table of contents of the course reader is in this style, and you can use it as a model. Also, they not only support the main conclusion, but consider alternative points of view as well and show why they are inferior.
Good analysis is specific.
Readers will be suspicous that you don't know what you are talking about. Be careful to cite the sources you draw on. There is no limit to the number of references you can use. However, good use of sources is not simply a matter of quantity, but of quality. In assessing the quality of a source, you will want to consider who is writing it, when it was written, what kind of publication it appears in, and how appropriate these factors are to the reason for the citation.
