"Primary sources . . . are defined as the direct evidence of a time and place that you are studying – any material (documents, objects, etc.) that was produced by eyewitnesses to or participants in an event or historical moment under investigation. Secondary sources, in contrast, are interpretations – often generated by scholars – that are based upon the examination of multiple primary sources." (from Primary Source.org)
