When you write a paper or give a presentation you need to have a topic( thesis topic), and you must reference your sources according to one citation manual.
Take a moment to think about your topic.
Define your topic by asking yourself a set of questions. Turn your topic into a research question (a thesis topic).
Think of words and phrases to use in a search for information regarding your topic. If nothing works, change your search terms to find more specific or more general information. Remember you can always ask for research help from a librarian.
