In an effort to create the best possible course, I have decided to take a Udemy course. This will help me to understand the dynamics of Udemy. I'm taking an art history class. It is Art History Renaissance to 20th Century with Kenney Mencher. A couple of students questions mentioned an assigned textbook. However, I do not see any mention of a textbook. I assume I'm unaware of where to find the book. can someone please tell me how to find it?
