Here's a basic research approach and sources to consider along the way. Think of these sources as pieces of evidence that support your argument. Research writing is "recursive," in which drafts can be opportunities to swap weaker sources for stronger ones.
1. Explore topic context & primary sources (news or non-library sources)
2. Learn the background (WorldCat Discovery: books)
3. Discover scholarly conversations (library databases: journal articles)
4. Support your argument (source citation)
5. Rinse, repeat; drafts & revisions (research librarians, writing center)
