With respect to historical studies, a secondary source is a record that was NOT created at the time the event being described or otherwise recorded took place or a record that was NOT created shortly afterwards by someone who personally witnessed or participated in the event. For the purposes of the SCRCA Project, potentially useful / interesting historical secondary sources are likely to include reference books and magazine / journal articles that are not contemporary with the period being described. The terms secondary sources and secondary source material are synonyms - i.e. they mean the same thing. See also primary source.
