You will need articles from peer-reviewed journals for your research papers. The following theological databases are great places to start to find your articles. Start with a keyword search, and limit your results to "peer-reviewed."
Some of the articles you find will have full-text PDFs that you can read and download. Others will only have the citation information for the article; in that case, you will need to search for the journal in our catalog to find its call number, find the physical copy of that volume in our stacks, and scan the article at one of the library book scanners (journals cannot be checked out). Good luck with your research, and remember that you can always ask at the Reference Desk for help.
