Research
Research is the most important part of the National History Day Ⓡ process. Historians conduct research using two kinds of sources: primary sources and secondary sources.
Primary Sources
The Library of Congress defines primary sources as "the raw materials of history—original documents and objects that were created at the time under study." Primary sources provide multiple perspectives on your topic from people who experienced it firsthand. Examples of primary sources include:
- Letters
- Journal or diary entries
- Newspaper articles (from the time period)
- Political cartoons
- Maps
- Photographs
- Government records
- Oral histories
- Original film footage (if applicable)
- Original audio clips (if applicable)
Secondary Sources
If primary sources are the raw materials of history, then secondary sources are the finished products. They are accounts of your topic that were created by people who did not experience it firsthand. Secondary sources provide descriptions, summaries, analysis and interpretation of your topic using primary sources as evidence. Examples of secondary sources include:
- History textbooks
- Books or monographs
- Scholarly journal articles
- Newspaper articles (from after the time period)
- Interviews with scholars or other experts
- Documentary films
- Podcasts
