- Primary sources are produced by participants in a specific event or time period, or witnesses to an event or period in history. Examples include: contemporary news and magazine articles, interviews, original photographs, memoirs and autobiographies, as well as material objects
- Secondary sources are typically books and articles written about a topic, by a non-participant in an historical event or time period. Authors of these works utilize evidence to formulate a thesis and develop a conclusion based on this evidence, which often are primary sources
Searching TIP: Many primary sources can be found within the bibliographies and notes in secondary sources.
If you are unsure about a source, check with your professor or a research librarian to determine whether it can be considered primary or secondary.
