If you are off-campus, log into Google Scholar using your CofC g-mail so that you can access articles provided by the CofC libraries. Remember: although this is Google Scholar, you still need to be vigilant about the authority and quality of literature found here.
Go to the advanced search and check "language & literature" from the "Journal Filter," (you may need to scroll down to see this). Remember, JSTOR only offers older articles from a limited, but quality, list of journals.
Be careful with this one. It provides online access to canned criticism -- mainly excerpts from actual journal articles and books. Many profs do not allow you to cite this directly but it can lead you to the real stuff.
