Primary Sources are immediate, first-hand accounts of a topic, from people who had a direct connection with it. Primary sources can include:
- Texts of laws and other original documents.
- Newspaper reports, by reporters who witnessed an event or who quote people who did.
- Speeches, diaries, letters and interviews - what the people involved said or wrote.
- Original research.
- Datasets, survey data, such as census or economic statistics.
- Photographs, video, or audio that capture an event.
- Raw data.
Secondary Sources are one step removed from primary sources, though they often quote or otherwise use primary sources. They can cover the same topic, but add a layer of interpretation and analysis. Secondary sources can include:
- Most books about a topic.
- Analysis or interpretation of data.
- Scholarly or other articles about a topic, especially by people not directly involved.
- Documentaries (though they often include photos or video portions that can be considered primary sources).
