What is a Secondary Source?

Secondary sources are created by individuals who were not direct participants in an event. For example, books on Purdue University history are secondary sources because the author analyzes, interprets, retells, or explains events for which he was not present and did not personally witness.  Secondary sources help you understand a topic and give you different views of historical people, events, and occurrences.
