Before you begin actively researching your topic, you will need to think about the types of sources that are available. Information comes to us from many sources - books, magazines, journals, newspapers, radio, television, websites, multimedia sources, etc... The type(s) of information you need will depend on the nature of your potential topic.
We have created a research guide specifically to help you determine your information need. It covers source types, offers tips on refining your topic, and will even help you determine your final research question.
If you need additional help, you can always contact a librarian, who can help you determine which sources to use.
