What types of literature or writing do you think should be addressed in college Intro to Literature classes?

I personally think that the types of literature that should be used is writing that makes a reader think. Not just simply think but actually make them look outside the box. I find that reading an author's work that has a meaning hidden behind the words is enjoyable. It gives reader's a chance to focus on where the author is coming from. Personal experiences also make for good stories. These stories have lots of emotion packed into each and keep reader's attention from beginning to end.
