A primary source usually refers to a first-hand account of a period/event/finding that the author directly experienced/observed. They do not need to be written by the individual you are writing about, they can be written by any individual that witnessed the event. In some cases, if you cannot access an original document, you may find a digital copy online. Every discipline defines primary source material slightly differently.
Secondary sources analyze, synthesize, and/or interpret original primary material.
