The difference between primary and secondary sources
Primary sources are "actual records that have survived from the past, such as letters,
photographs, articles of clothing." Secondary sources are "accounts of the past created by people writing about
events sometime after they happened."
[Library of Congress definition]
Primary sources can be materials that were published (autobiographies, advertisements, maps, laws, court decisions, etc.) or unpublished (personal letters, diaries, journals, wills, etc.). Primary source materials also include oral traditions/histories (accounts from people with firsthand knowledge of events) and visual artifacts (photographs, clothing, tombstones, etc.).
Secondary sources may also be published or unpublished, based upon oral tration, or expressed through a the medium of material culture, but they are created after (usually long after) an event.
