Primary Sources are a first-hand account of a topic by people who were part of the original study or event. It is always factual and not interpretive. This is also called original research.

Primary Sources can include:

• Original research of scientific experiments or clinical trials
• Original first-hand account of an event or time-period
• Survey data such as census or economic data
• Speeches, diaries, letters or person accounts
• Text of law or original documents

Secondary Sources can use information from primary sources but normally interpret or analyze the data or information of the study, event or creative work.

Secondary Sources can include:

• Scholarly or other articles about a topic but written by someone not directly involved
• Analysis or interpretation of data or event
• Documentaries
• Most books about a topic or event
