Primary sources contain information which is original, and can often be the most up-to-date information available. Primary sources will be written or produced by people who were directly involved in the research or events being presented and described in those sources.
Primary sources are records that provide first-hand testimony or evidence of an event, action, topic, or time period. Primary sources are usually created by individuals that directly experience an event or topic, and record their experience through photographs, videos, memoirs, correspondence, oral histories, or autobiographies.
Secondary literature is the mass of published materials that interpret, evaluate, or analyse the evidence derived from primary sources. Secondary sources provide a factual context or interpretative framework for your analysis.
