Essays / Annotated bibliography; Need help to find sources [3]

I have to write an annotated bib for my literature class and I have no clue how to start it. I wanted to do something on hubris or chivalry but I'm unsure of a thesis statement. I also cannot find any sources that support anything on those topics. Any help you can provide would be greatly appreciated. I hope this is the right forum i wasn't sure where to put this.
