Primary sources typically consist of eye-witness accounts of an event or topic. The creators of primary sources witnessed or recorded the events they experienced first-hand.
Primary sources can also include sources like autobiographies, memoirs, and oral histories, that were created after the events by participants or observers of the events.
Primary documents are often accessible online in electronic formats - for example, a digitized copy of a historical treaty - but still retain their status as primary documents based on the nature of their content not their format.
Depending on the discipline (psychology versus history, for example) a primary source can be different. In history, primary sources often include original documents or other first-hand accounts of an event. By contrast, in literature, a primary source include original works like novels, poems, or dramatic plays.
In contrast to primary sources, secondary sources make use of primary sources to review, analyze, and provide commentary on a topic. Secondary sources are typically created by individuals or groups who were not eye-witnesses to an event, but make use of the work and accounts of others to examine a topic in detail.
