How to Write In-Text Citations

Before writing a single citation, check your assignment rubric or syllabus to see which style guide you must follow. MLA style is typically used in the humanities (English, Arts, Philosophy) and focuses on the author and page number. APA style is standard for social sciences (Psychology, Education, Sociology) and emphasizes the author and the year of publication. Chicago style is common in history and often uses footnotes, though it also has an author-date system. Selecting the wrong style can lead to significant point deductions, even if your information is accurate.

For every source you use, you must find specific metadata. For MLA, you need the author's last name and the exact page number where the information appears. For APA, you need the author's last name, the publication year, and the page number (specifically for direct quotes). If a source has no author, use the first few words of the title. If there is no page number, such as on a website, you may omit it in MLA or use a paragraph number in APA. Having these details ready prevents interruptions in your writing flow.

You can credit a source in two ways. A parenthetical citation places all the required information in parentheses at the end of the sentence. This is the most common method as it keeps the focus on the data. A narrative citation integrates the author's name directly into your sentence. Use narrative citations when the author is a recognized expert or when you want to vary your sentence structure. Both methods are equally valid, and a strong essay typically uses a mix of both to maintain reader interest.

Apply the specific punctuation rules for your style. In MLA, do not use a comma between the name and page number: (Smith 42). In APA, always include a comma and use 'p.' for page numbers: (Smith, 2023, p. 42). If you are using a narrative citation in APA, the year must immediately follow the author's name: Smith (2023) argued that... Ensure that every in-text citation corresponds to a full entry on your Works Cited or References page at the end of your document.
