VoS or Voice of the Shuttle is a unique and very useful website for anyone interested in the humanities. Their page devoted to American Literature is worth exploring if you have even a slight interest in American Literature at a deeper level than simply reading a good story.
The American Literature page contains links to sites concerned with American Memory to those devoted to individual American Authors to sites that relate to American Literature Syllabi and Conferences.
So what does the allusion Voice of the Shuttle refer to? It is a reference to the myth of Tereus and Philomela and the page devoted to the allusion is a fun exploration in and of itself.
