Primary sources in the Humanities are records that provide first-hand testimony or evidence of an event, action, topic, or time period. Primary sources are usually created by individuals who directly experience an event or topic, and record their experience through photographs, videos, memoirs, correspondence, oral histories, or autobiographies.

Common Examples of PRIMARY Sources in the Humanities:
Letters, diaries, memoirs, speeches, interviews, photographs, notes, subject files, oral histories, autobiographies, travelogues, pamphlets, newspapers, newsletters, brochures, government documents including hearings, reports and statistical data, military service records, manuscripts, archival materials, artifacts, architectural plans, artistic works, works of fiction, music scores, and sound recordings.

Primary sources in the Social and Natural Sciences, also referred to as primary research, report a researcher's methodology, results, findings and data from their own original research, ideas, experiments, or scientific discoveries.

Common Examples of PRIMARY Sources in the Social and Natural Sciences:
Published research findings, case studies, conference papers, patents, lab notebooks, surveys, and raw data.

What is a Secondary Source?

Secondary sources interpret, analyze, critique, or comment on information found in primary sources and put them into context. They are usually written by individuals who did not experience the events firsthand. A key component of many secondary sources is the presence of a thesis statement or argument made by the author.

Common Examples of SECONDARY Sources:
A book that analyzes the attack on the Alamo, a scholarly journal article critiquing a work of art, reviews of previously published research, literature reviews, biographies.

Tertiary Sources

Tertiary sources compile, distill, and summarize factual information obtained from other (usually secondary) sources. They often provide a broad overview of a topic. A tertiary source does not contain a thesis or argument. The absence of a thesis or argument is a key difference between a tertiary source and a secondary source. Many tertiary sources are also referred to as reference sources.

Common Examples of TERTIARY Sources:
Almanacs, dictionaries, encyclopedias, handbooks, directories, manuals, textbooks.
