You are writing it because I really, really want to know about your topic and am incapable of learning about it on my own. A single source is adequate, as long as it's a good one. Encyclopedias are solid academic references. Citing Webster's dictionary makes you sound educated. A search engine is all you need to find really good information.
All web sites are equally great.
The process of research consists of stitching together blocks of information. A single citation at the end of a paragraph is adequate acknowledgment that you got the whole thing from one of your sources. Once you've got your first draft all pasted together, tinkering with spelling and punctuation or adding a few pretentious words from a thesaurus constitutes a second draft. The standard of quality you have to meet is what you did in high shcool. Though, with your help, all of us will probably learn something new about your topic, our primary focus in this class is the process of researching and constructing a solid academic paper.
