MLA, 9th Citaton Examples

An academic journal is a publication who's audience is other experts in the same field. Use this example anytime you are referencing an academic or scholarly article, usually found in a library database or open source journal. 

A DOI, or Digital Object Identifier, is a string of numbers, letters and symbols used to uniquely identify an article or document, and to provide it with a permanent web address (URL). A DOI will help your reader easily locate a document from your citation. Not all articles will have a DOI.

Use the library A-Z list to find reliable academic journal articles.

In-Text Citation

What Is In-Text Citation? 

In MLA, in-text citations are inserted in the text or body of your document to briefly cite the source of your information. Brief in-text citations point the reader to the full information in the Works Cited list at the end of your document. 

When using MLA format, follow the author - page number method of in-text citation. For this method include the author and page number within the body of your document and include a corresponding reference in the list at the end of the document. This method allows the reader to identify sources used in your document, then easily locate them in the alphabetical Works Cited list. 

Create an in-text citation whenever you quote another work or paraphrase another work in your own words.

See the MLA Style Blog for an In-Text Citations Overview

In-Text Citations Have Two Formats

  1.  Parenthetical - the author name and page number appear in parentheses. For example: Vaping exposes the lungs to hundreds of toxic chemicals and is highly addictive to the still developing brain (Simerlein 27). 
  2. Citation in Prose or Narrative style - the author name appears in the text of the sentence and the page number appears in parentheses at the end of the sentence. For example: Simerlein notes that vaping exposes the lungs to hundreds of toxic chemicals and is highly addictive (27). 

Paraphrasing and Quoting: What Is The Difference? 

There are two ways to integrate sources into your assignment: 

  1. Paraphrasing is used to show that you understand what the author wrote. You must reword the passage, expressing their ideas in your own words, and not just change a few words here and there. Make sure to include an in-text citation. See this page of the guide for paraphrasing tips. 
  2. Quoting is copying a selection from someone else's work, phrasing it exactly as it was originally written. When quoting, place quotation marks (" ") around the selected passage to show where the quote begins and ends. Make sure to include an in-text citation. 

Signal Phrases

Readers should be able to move from your own words to the words of your references without feeling an abrupt shift. Signal phrases provide clear indicators to prepare the reader for the quotation/paraphrase. In MLA verbs are used in the present tense when introducing a quote or paraphrased section. Choose verbs that reflect the author's intent. Some common signal phrases are: 

  • Argues
  • Believes
  • Claims
  • Denies
  • Explains
  • Observes
  • Reports
  • Thinks
  • Suggests
  • Writes
  • Emphasizes the importance of

Short Quotations

MLA defines a short quotation as four typed lines or fewer or prose of three lines of verse in your text. 

  • Include the quote in the sentence or paragraph and enclose it within double quotation marks: "......".
  • Include the author and page number for the in-text citation. 
  • If the author is introduced as a citation in prose, then add the page numbers in parentheses at the end of the quote. 
    • For example, Mohseni demonstrates how to " ......." (76). 
  • If the author is not introduced as part of the text then a parenthetical citation is needed. Include the author and page number after the quotation. 
    • For example, "...energy industry fundamentals is the best course this Fall" (Mohseni 76). 

Note: If page numbers are not available (e.g., webpages, some e-books, etc), you do not include it in the in-text citation

Long (Block) Quotations

If a quotation is longer than four typed lines, treat it as a long or block quotation: 

  • Do not use quotation marks to enclose a block quotation. 
  • Start a block quotation on a new line and indent the whole block 0.5 inches from the left margin. 
  • The line before the block quote should indicate the start with a colon (:).
  • Double-space the entire block quotation. Do not add any extra space before or after it. 
  • Either (a) cite the source in parentheses after the quotation’s final punctuation or (b) cite the author in the narrative before the quotation and place only the page number in parentheses after the quotation’s final punctuation. 
Block quotation with parenthetical citation:

Researchers study how stress affects nursing students: 

Nursing students often face significant stress due to the demanding nature of their coursework, clinical rotations, and high-stakes examinations, which can lead to feelings of burnout and decreased academic performance if not properly managed. To manage stress during nursing school prioritize self care with meditation, yoga or breathing exercises, practice effective time management strategies by creating to-do lists, build a support network of peers and mentors, and don't be afraid to ask questions during class and at clinical rotations. (Reddington 9)


Block quotation with narrative citation: 

Grace Reddington describes how stress affects nursing students: 

Nursing students often face significant stress due to the demanding nature of their coursework, clinical rotations, and high-stakes examinations, which can lead to feelings of burnout and decreased academic performance if not properly managed. To manage stress during nursing school prioritize self care with meditation, yoga or breathing exercises, practice effective time management strategies by creating to-do lists, build a support network of peers and mentors, and don't be afraid to ask questions during class and at clinical rotations.
