What is a primary source?

Primary sources refer to original events, documents and artifacts. Examples include: newspaper articles, photographs, and diaries. These are the works that are analyzed and interpreted to create secondary sources. For more information on finding primary sources see our Guide to finding primary sources.

Why use secondary sources?

Secondary sources can provide you with background information and offer analysis of the event or work by those removed one or more steps from the event or work itself.  Scholarly articles are written by experts studying in a particular field, offering credibility to your research by providing interpretation of material by scholars. Secondary sources look beyond a particular event or artifact and can broaden your perspective and research.   They can also provide historical perspective based on other events that have taken since the original event or work.

How can I tell if something is a secondary source?

As with any research, examine the document or article carefully for accuracy and credibility. Use the following questions to help you determine whether or not you are using a credible secondary source:

Authors
