What is the difference between a primary and secondary source?
A primary source is the original document. For example, if you are writing a paper on the French revolution, then letters and thoughts published from folks who participated in the French revolution is a primary source. A secondary source is a source that cites primary sources to back its claims, it may also cite some other secondary sources. Your paper would be a secondary source -- you will cite primary and other secondary sources to make your points about the French revolution.
