Finding Primary Sources

A guide to finding primary sources for History research.

Citing Primary Sources

Citing primary sources can be difficult, especially when you are using a source that has been digitized or reproduced on a website.  Obviously, a letter from 1652 that you see online is not the real thing!  So how do you cite it in your paper? 

In the bibliography or works cited page:

  • Remember that Primary Sources should be separated from Secondary Sources in your bibliography. See the Handbook for Historians to get correct bibliography formats.

In your footnotes or endnotes:

The Handbook for Historians section citing sources suggests citing a primary source within your footnotes as follows:

Author of original document, first name first, “Title of document,” Date of document, Title of Web Site where document is found, Author, Editor, or Producer of site, accessed date, URL.
