Letter by Cesare Borgia to Isabelle d'Este.

Primary sources provide first-hand testimony or direct evidence concerning a topic under investigation.

They are created by witnesses or recorders who experienced the events or conditions being documented.

From: "Primary sources at Yale"

Think about what kinds of primary sources might be related to your topic:

Nowadays even your social media can be a primary source, because it reflects the reality of the times.

1. Start with what you already have: to uncover references to primary sources. Consult your:

• class notes
• course readings
• bibliographies of your textbook, journal articles, or other secondary sources
• historical encyclopedias

They can also help you identify relevant historical figures, authors, or keywords for searching library databases

2. Use the library catalogue to find books and other materials.

To find primary sources on your subject, combine keywords for different kinds of primary sources with keywords for your topic.

Examples:

reformation sources

world war 1914 correspondence

national socialism documents
