Check out this video from Suffolk County Community College Library to understand how primary, secondary, and tertiary sources vary by discipline.
Before you start any research on your topic, you must develop some background knowledge including facts, dates, and names of important people, places, or theories. Books and websites can provide you with that knowledge.
This is important because:
Remember, background information is always a starting point for research, not an ending point.
In addition to being a great place to start exploring an unfamiliar topic, Wikipedia is considered a tertiary source. Writers of tertiary sources synthesize information from secondary sources and strive to report them in a tone that is as unbiased and neutral as possible.
Some tertiary sources are cited in academic research and others are not. This practice varies by discipline so contact your instructor or a librarian with questions!
