"...if art speaks clearly about something relevant to people's lives it can change the way they perceive reality."
Judy Chicago (b.1939), U.S. artist. As quoted in The Political Palate, ch. 3, by Betsey Beaven, et al.(1980).
What are primary sources?
Primary sources are original resources created at the time historical events occurred or well after events in the form of memoirs and oral histories. Primary sources may include letters, manuscripts, diaries, journals, newspapers, speeches, interviews, government documents produced by government agencies such as Congress or the Office of the President, photographs, audio recordings, moving pictures, video recordings, research data and objects or artifacts such as works of art or ancient roads, buildings, tools, and weapons. These sources serve as the raw material to interpret the past and when they are used along with previous interpretations by historians, they provide the resources necessary for historical research.
