You will find many useful books in the library. Try a few keywords (no more than three) to find what you need. You can browse a list of books that have been classified as "realism in literature." However, there are many other books available. When you find a book that looks promising, go up to the stacks and try browsing around in the same area as books are shelved by subject and author.
Again this is a very small sampling of what is available in the library.
