In this article, the author describes how he gives students in his English 349, Editing and Publishing, at the University of Wisconsin-Stevens Point real-world editing and publishing experience by letting them form their own publishing company--the Cornerstone Press. In this class, students write multiple drafts of publishable articles and help one another to edit them. They research and make a presentation to the entire class about some aspect of editing or publishing. They undertake an individual publishing project. And, they work with their classmates to select, edit, design, print, bind, and market 500 to 1,000 copies of one or more books.
