The readings are central to this class. The required books are available at the bookstore. Required essays not included in the books are available through the course Moodle site. Each weekly listing will indicate where you can find each reading (or will include a link directly to the reading).
If a reading doesn’t say “suggested” in front of it, then it is a required weekly reading. The suggested readings are there for your interest, for fun, or for if you want to dig deeper into a subject.
