Understanding Primary and Secondary Sources

Jun 18, 2025

Overview

This lecture explains the differences between primary and secondary sources, highlighting their roles in academic research across various disciplines.

Types of Sources

  • There are two main types of sources: primary and secondary.
  • Primary sources are the direct, original evidence or first-hand accounts for a discipline.
  • Secondary sources are materials created using primary sources, such as books and articles.

How Disciplines Define Sources

  • The definition of primary and secondary sources varies by discipline.
  • In history: primary = first-hand account; secondary = article about that account.
  • In literature: primary = novel or poem; secondary = article about the work.
  • In science: primary = empirical study; secondary = article about someone else's study.

Determining Source Type

  • Whether something is a primary or secondary source depends on its content and your research focus.
  • The same source can be primary in one context and secondary in another.

Example: The Ukrainian Terror-Famine

  • Historians use first-hand letters as primary sources to study the Terror-Famine.
  • A scholar's article using those letters is a secondary source about the event.
  • If studying the scholar, that same article becomes a primary source about the scholar.

Value of Primary vs. Secondary Sources

  • Primary sources are not inherently better than secondary sources.
  • Secondary sources provide useful analysis and can offer insights not obvious from primary sources alone.
  • Both source types contribute to building new knowledge in academic research.

Key Terms & Definitions

  • Primary Source โ€” Original, direct evidence or first-hand account related to a topic.
  • Secondary Source โ€” Material created by analyzing or interpreting primary sources.

Action Items / Next Steps

  • Review examples of primary and secondary sources in your discipline.
  • Reflect on how you plan to use your sources for your research topic.
