Primary source [from Electronic source using APA 6th ed.]
A document or artefact produced during the historical period being researched.
Primary sources can be textual or visual. They include books, pamphlets, magazine and newspaper articles and conference proceedings published during the period being researched. Maps, ephemera such as advertisements, photographs, archival documents, museum artefacts and audio-visual resources such as newsreels may all be considered primary sources. They may be accessible in their original format or digitised. Exact definitions may vary in different subject areas, so it is advisable to seek advice from your lecturer to identify the most suitable primary sources to incorporate into an essay or dissertation.
