How to Cite a Primary Source in MLA Style
Citing primary sources is a crucial aspect of academic writing, particularly in the humanities. Primary sources are original materials that provide firsthand information on a subject, such as historical documents, interviews, and personal narratives. When citing these sources in MLA (Modern Language Association) style, it's essential to follow the guidelines outlined in the MLA Handbook (8th edition) to ensure accuracy and consistency. In this article, we'll explore how to cite a primary source in MLA style, including in-text citations, Works Cited pages, and examples of common primary sources.
Understanding Primary Sources
Primary sources are unique to the field of study and can be classified into several categories. They include:
- Historical documents: Letters, diaries, speeches, and other written or printed materials from a specific time period.
- Interviews: Personal conversations or questionnaires that provide firsthand information on a subject.
- Personal narratives: Memoirs, autobiographies, or oral histories that share an individual's experiences.
- Artistic works: Original compositions, such as music, poetry, or visual arts, that convey a message or tell a story.
Citing Primary Sources in MLA Style
When citing primary sources in MLA style, you need to include the author's name, title of the source, publication date, and publication information. For primary sources without an author, you can use the title as the citation. Here's a general outline of how to cite a primary source in MLA style:

- Author's Last Name, First Name. Title of the Source. Publication Date. Publication Information.
- Example: Johnson, Samuel. A Dictionary of the English Language. 1755. Print.
Citing a Primary Source with Multiple Authors
If the primary source has multiple authors, you need to separate their names with commas and use the word "and" before the last author. If the source has more than three authors, you can shorten the citation by using "et al." (meaning "and others") after the first author's name.
- Author's Last Name 1, First Name 1, Author's Last Name 2, First Name 2, et al. Title of the Source. Publication Date. Publication Information.
- Example: Smith, John, Jane Doe, and Richard Lee. A Study on Climate Change. 2020. Print.
Citing a Primary Source without an Author
If the primary source does not have an author, you can use the title as the citation. If the title is long, you can shorten it to the first word or a few words that best describe the source.
- Title of the Source. Publication Date. Publication Information.
- Example: Declaration of Independence. 1776. Print.
Citing a Primary Source in a Book or Journal
When citing a primary source in a book or journal, you need to include the author's name, title of the source, and page numbers. Use the MLA format for in-text citations, and include the publication information on the Works Cited page.

- Author's Last Name, First Name. "Title of the Source." Title of the Book or Journal. Publisher, Publication Date, pp. Page Numbers.
- Example: Johnson, Samuel. "A Dictionary of the English Language." A Collection of Dictionaries. Oxford University Press, 2005, pp. 12-15.
Citing a Primary Source in a Database or Online Archive
When citing a primary source in a database or online archive, you need to include the author's name, title of the source, and database or archive information. Use the MLA format for in-text citations, and include the publication information on the Works Cited page.
- Author's Last Name, First Name. "Title of the Source." Title of the Database or Archive. Publisher, Publication Date, Web. Date of Access.
- Example: Smith, John. "A Study on Climate Change." Environmental Studies Database. Oxford University Press, 2020, Web. 10 Feb. 2023.
Creating a Works Cited Page
A Works Cited page is a list of all the sources cited in your research paper. It provides a clear and organized record of the sources you've used, making it easier for readers to locate them. When creating a Works Cited page, make sure to:
- Double-space the entries.
- Indent the first line of each entry five spaces.
- Use a hanging indent for subsequent lines of each entry.
- List the entries in alphabetical order by author's last name.
