I can't find a good discussion online comparing Ralph Waldo Emerson and Nathaniel Hawthorne, can you help?

I’m finding it difficult to find viewpoints in general comparing these two. Google results keep referring me to collections of American literature and that is not what I need. I need to find discussions or periodicals posted online that will serve as references and to jump start an idea in my head for a section of a paper that I am doing. Any help would be appreciated. I just need ideas, or at least a place online that will serve as a muse of sorts. If you have thoughts on this as well, I would love to hear them.
