Primary sources are the raw materials of research. They provide firsthand access to words, images, or objects created directly by the persons involved in the activity or event. The value of primary sources is that they allow the researcher to get as close as possible to the original work. It is important to note that the types of information that can be considered primary sources may vary depending on the subject discipline, and also on how you are using the material. Time is also a defining element.
Primary sources often enable the researcher to experience the flavor of the original event or information, rather than relying upon someone else’s interpretation. Keep in mind that primary sources, because of their first-hand nature, may not be completely well-reasoned, objective, or accurate.
