Primary sources are always original, first-hand information. They are usually created at the time a specific event occurred. Sometimes, though, primary sources are told later by someone who witnessed the event. What matters is that the person giving the information actually experienced what he or she is telling about. Primary sources give an eyewitness account of what life was like at a certain time. They sometimes show the witness’s opinion about an event. Primary sources can be letters, diary entries, audio or video clips, personal interviews, photographs, property deeds, court records and even objects from a certain time and place.
