A historical newspaper, magazine, yearbook, or other traditionally published item can be a primary source because it tells you how the public reacted to an event or topic at the time that it was happening.
How to Cite: Use your style guide's format for a normal newspaper or magazine citation. If you found the source in an archives or on the website of a specific archives (as opposed to a database), be sure to include repository information in accordance with their preferred citation. These examples use the Chicago Manual of Style citation format.
Example Found Online: "Extract of a letter from Pittsburgh, Nov. 28," The Vermont Gazette, January 4, 1790, 3. America's Historical Newspapers.

Letters, diaries, and eyewitness reports are often published in books or pamphlets. This could be a modern anthology of letters or a diary that was published hundreds of years ago.
How to Cite: Use your style guide's format for citing the work in which the primary source is published, such as a book or pamphlet. Keep in mind that for very old works, information that you need such as author, publication date, and publisher may be missing or located in a different place than you're used to within the source. If accessed through an archives or special collections library, be sure to include repository information in accordance with their preferred citation.
Example (modern book): Letter from Elizabeth Barrett to Robert Browning, 11 January 1845. The Letters of Robert Browning and Elizabeth Barrett Browning, 1845-1846. Edited by Robert Browning and Elvan Kintner. Cambridge: Belknap Press of Harvard University Press, 1969.

These are what you may think of as traditional archival materials--original copies of letters, diaries, manuscript writings, and more that are unpublished and unique to the repository in which they are found.
How to Cite: These can be the trickiest to cite because every document is different. Focus on including as much of the key information about the source as possible, rather than filling in a formula. You will rely most heavily on a repository's preferred citation when citing these sources. In Chicago Manual of Style, refer to section 14.232 ("Manuscript Collections") and proceeding sections.
