PRIMARY SOURCES

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.

Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later.

The medium of the primary source can be anything, including written texts, statistics, objects, buildings, films, paintings, cartoons, etc. What makes the source a primary source is when it was made, not what it is.

Examples of primary sources include, but are not limited to: 

• Anatomical drawings (ex. Vesalius's Fabric of the Human Body)
• Etchings, drawings, or paintings (ex. The Anatomy Lesson of Dr. Nicolaes Tulp)
• Instruments, tools, artifacts (ex. Bone Forceps from Ancient Greece)
• Written works (ex. On the Sacred Disease)
• Patient case histories written by doctors (ex. Studies on Hysteria)
• Patient narratives of their experiences (ie. diaries, letters, autobiographies, drawings, poems. ex: The Yellow Wallpaper)
• Newspaper articles (ex. an article about SARS in the Toronto Star during the 2003 outbreak)
• Legal documents (ex. court transcripts of the Tobacco Master Settlement Agreement)
• ... the list goes on and on!

SECONDARY SOURCES

A secondary source interprets and analyzes primary sources. These sources are one or more steps removed from the event. Secondary sources may have pictures, quotes or graphics of primary sources in them. 

Examples of secondary sources include:

• Articles published in scholarly journals (ex. Better Science and Better Race?: Social Darwinism and Chinese Eugenics)
• A history textbook (ex. History of Medicine: a Scandalously Short Introduction)
• A book about the history of medicine (ex. Evolution : the history of an idea)

A Word About Context... 

If you're having trouble deciding whether something's a primary source or a secondary source, ask yourself this question: Why Am I Using It? 

For example, if I'm looking at a 1994 book on HIV/AIDS, it's a secondary source if I'm using it to inform my knowledge of HIV/AIDS science and research. But, if I'm interested in how doctors and scientists were researching and writing about HIV/AIDS in the mid-1990s and what this book tells me about them, it's a primary source.
