Hi Allyson, I would suggest trying some literary databases, as the information will be more targeted to your topic than a general search. Here's a basic search I did in our Literature Criticism Online database: link and another one from Literary Reference Center: link. We have a lot of books about Flannery O'Connor, which you can see here: link, and when you come in to the library, we can help you find them. I hope this helps get you started--let me know if you have more questions :)
