You may only use the texts assigned on the course syllabus, and not any sources from outside of the course. Resist the urge to cut and paste from other sources, either literally or figuratively by using other people’s ideas. If I find that you have used other people’s ideas (including Wikipedia, Amazon reviews, book jacket descriptions, etc.), I will not accept the assignment because I will not be able to consider it your own work.
