Primary Sources: A primary source is an original object or document created at the time the historical events occurred. It is the raw material or first-hand information. Primary sources include historical and legal documents (i.e. letters, memoirs, diaries, newspapers, speeches, interviews), photographs, eyewitness accounts, results of an experiment, statistical data, pieces of creative writing, and art objects. In the natural and social sciences, the results of an experiment or study are typically found in scholarly articles or papers delivered at conferences, so those articles and papers that present the original results are considered primary sources.
Secondary Sources: A secondary source is something written about a primary source. Secondary sources include comments on, interpretations of, or discussions about the original material. You can think of secondary sources as second-hand information. If I tell you something, I am the primary source. If you tell someone else what I told you, you are the second source. Secondary source materials can be articles in newspapers or popular magazines, book or movie reviews, or articles found in scholarly journals that evaluate or criticize someone else's original research.
