Google Scholar is a useful tool for searching through a very broad scope of articles; however, be aware that they aren’t actually all “scholarly.” By using this Google Scholar link [https://scholar.google.com.au/?inst=440242604988873961], you will be able to see all of the resource available through XU's resources--a much wider selection than basic Google Scholar.
Look for the text “Get It @ XU” instead of the usual “Get It” button to search for the full text of articles that don’t have an included PDF. It is sometimes found under the “more” link below the record.
Use interlibrary loan to request articles for which Xavier does not have access.
