MLA Format Citation Style Guide: How to Cite Sources in MLA Format
The Modern Language Association (MLA) style is one of the major formatting styles used in academic writing. MLA emphasizes parenthetical in-text citations that lead to an alphabetized list of works cited. MLA style provides writers with a systematic way to document sources and acknowledge ideas and text that they have used in their writing. The in-text citations allow readers to link sources to specific passages within the document.
Overall Purpose of Internal Citations
Internal citations serve two main purposes. The first is to credit authors for words, ideas, data, or other content that is not the writer’s own. Simply restating someone else’s words or ideas without citation would be considered plagiarism. Internal citations attribute borrowed content to its original source.
The second purpose is to allow readers to easily locate the full bibliographic information for cited sources. For most academic papers, readers are likely interested in exploring the sources further. Internal citations direct readers to the bibliography so they can find publications, websites, interviews and other works that influenced the research and argument.
Formatting In-Text Citations
In MLA style, parenthetical citations include the last name of the author followed by a page number if a specific page is cited. If no page number is available, use a paragraph number or an abbreviated heading/title.
For direct quotations, include the author’s last name, a space, and the relevant page number in parentheses after the quoted material:
As Clarke stated in his research, “All organisms interact with their environment in some manner” (23).
For paraphrasing or referring to a person or idea without a direct quote, include just the last name in parentheses:
Many scientists agree that environment plays an important role in natural selection (Clarke).
For internet sources that do not have page numbers, use a shortened version of the title within the citation. For example:
Web users now commonly track daily steps and calories burned (Dowsley).
Citing Multiple Works by the Same Author
To cite multiple works in the same parenthetical reference, separate the citations with a semi-colon:
Research shows increased focus and attention span with regular exercise (Smith 2014; Smith 2018).
Citing Authors with the Same Last Name
To differentiate between sources written by authors with the same last name, include the first initial in the in-text citation. For example:
Children benefit both physically and psychologically from participating in sports (L. Johnson 28) rather than spectating (T. Johnson 45).
Introducing Long Quotes
For direct quotations that are four lines or longer, set it off from the regular text by beginning a new line, indenting one inch from the left margin, and do not use quotation marks.
Omitting the author’s name from the introductory phrase allows for a smoother transition:
As one researcher found in a recent study on exercise habits:
Regular physical activity, even at a moderate level such as brisk walking 30 minutes per day,
showed significant cognitive improvements across all age ranges. Participants in the walking
group consistently outperformed their sedentary peers on tests of memory, problem-solving, and focus (Smith 45).
Placing Citations
Place citations as close as possible to the quoted or paraphrased information they reference. Put the in-text citation at a logical pause, such as at the end of a sentence or clause.
Research studies have come to similar conclusions about the mental health advantages of routine exercise (Clarke 23; Smith 29). Maintaining an active lifestyle is associated with decreased symptoms of depression and anxiety (Johnson 15).
Citing Indirect Sources
If referencing an idea or quote mentioned in a secondary source, such as in another publication or article, use “qtd. in” to indicate it was cited originally elsewhere.
As Glines asserted, “Exercise is preventative medicine” (qtd. in Smith 45).
Works Cited Page
The concluding section of a MLA research paper is titled “Works Cited” and consists of an alphabetized list of all sources cited throughout the paper. Each entry should begin with the author’s name and include as much bibliographic information as possible to identify the source. Book, periodical, web and other resource citations follow specific guidelines that maintain consistency.
Each source referenced in the paper must have a corresponding entry on the works cited page so readers can locate the full source information. Entries vary depending on whether sources are books, articles in periodicals, web pages, or other formats. Consistency in style and formatting allows readers to easily identify different types of sources.
Overall, implementing MLA citation style in research papers maintains academic integrity, credits sources appropriately, and helps readers follow up on cited works. The internal citations connect specific ideas and quotations to referenced sources, while the concluding works cited list completes the documentation. Mastering MLA format ensures research writing meets standard scholarly expectations.
