The introduction to Volume B of the Norton Anthology discusses how literature was influenced by the social/political culture of certain eras. One of the ideas talked about was urbanization in the 1800s and how that led to writing about "mysteries of the city" (937). In general, literature is closely tied to the concept of setting - either the home/travels of the author or the way a real place comes to life in his/her imagination.
If I think about contemporary Washington DC, I see a relationship between literature and setting in many ways. Dan Brown comes to my mind (ignoring the quality of the writing) because his latest book "The Lost Symbol" dealt with DC's monuments, heroes, and potential dark side. We as residents of the city are given a sense of pride when we read about it while readers who don't live in the city they are reading about feel a sense of wonder. What other values do we see in urban literature?
