The majority of your readings are in the following book, which is available at the Campus Bookstore for purchase, is on reserve at Stauffer Library, and is also available for purchase online (e.g. at Amazon)
Gerould, Daniel. Theatre/Theory/Theatre: The Major Critical Texts from Aristotle and Zeami to Soyinka and Havel. New York: Applause Theatre & Cinema Books, 2000 Cost: $24.32
You may also be able to find used copies of the Gerould book, because it has been used in several different iterations of this course.
A few readings will be collected in a package placed on reserve at the P&CC (this page will be updated when the readings are available).
