I am writing an essay using The Martian Chronicles- which I loved. But I need to use another book for comparison. A book about the appreciation of other cultures, like in Bradbury's book. It would be a great help if I knew of some other books. Thanks.

I can't think of a specific book off the top of my head, but for this kind of task you can't beat Google Books as a starting point.

(If you're not familiar with this, just go to http://books.google.com and type in some search terms. Many of the books that come up will have a "search inside" or "view sample pages" option. It will be hard work to sift through the books that are not relevant to your topic, but you're not afraid of a bit of hard work, are you...)

Well, I don't know about the "other cultures" part, but the book probably most similar to The Martian Chronicles is Winesburg, Ohio.
