Prototype Meaning

The most common meaning of primary source is an original piece of evidence that comes directly from the person, event, or subject being studied. People usually imagine a diary, letter, photograph, interview, official record, or original research data. Unlike a secondary source, which explains or analyzes existing information, a primary source provides direct material that researchers can examine themselves.
