MFA in fiction writing (or higher-level undergrad writing courses): Which textbooks are used?

Most of the advanced writing courses I am familiar with use examples rather than how-to texts. You could try googling "fiction writing syllabus" or "creative writing syllabus" to see what instructors ign for their courses. I learned a lot from an essay by Ursula K. Le Guin which I can no longer find, but it might be in her _Steering the craft : exercises and discussions on story writing for the lone navigator or the mutinous crew_.
