A primary source is something that was created and/or experienced at the time being studied. They provide a first-hand or eye witness account. Examples of primary sources include: historical documents, an artifact, a diary or journal, speeches, oral histories, photos, newspaper clippings, letters, etc. Reproductions of primary sources (remember, we won't have the originals) can often be found in books and on websites.
The LibGuide called Primary Source LibGuide will walk you through how to find and how to use Primary Sources.
