You should always consult with your instructor first about a research topic. She/he can provide valuable input. You may also want to do a general search on your area of interest to see what kind of information is available. We have many good online journal databases in a variety of subject areas.
You can log into any of these databases using your CMU Global ID and password.
Not sure which database(s) is best for your topic? Contact a librarian at the link below to discuss your ideas and receive additional guidance.
