MLA 9th Edition In-Text Citations Comprehensive Study Guide

Purpose and Core Principles of MLA In-Text Citations

  • Primary Function of In-Text Citations:

    • In-text citations provide direct credit to original authors for any paraphrased ideas or direct quotes incorporated into a paper.
    • They serve as the foundational mechanism to avoid plagiarism.
    • Every in-text citation corresponds directly to a full reference list entry on the Works Cited page at the end of the document.

  • Standard Two-Element Formatting Pattern:

    • MLA 9th Edition standard in-text citations rely on a two-element structure: the author's last name and the page number (or page range) where the referenced material is located.
    • Spacing and Punctuation: No comma separates the author's last name and the page number. Exactly one space is placed between the two elements (e.g., (Baron 193)).
    • Page Range Conventions: Do not use abbreviations such as "p." or "pp." before page numbers. Only the bare numerical values or range are used.
    • Specific Page vs. Works Cited Span: If a source spans multiple pages in the Works Cited list (e.g., pages 190–200), but the specific paraphrased idea originates from a single page, include only that specific page number (e.g., 193) in the in-text citation. If the paraphrased material spans multiple pages within the source, include the full page range (e.g., 4-5).

Formatting Patterns: Parenthetical vs. Prose (Narrative)

  • Parenthetical Citations:

    • Both key elements (author's last name and page number) are placed inside parentheses at the end of the sentence.
    • Sentence terminal punctuation (such as a period) is placed after the closing parenthesis of the citation.

  • Narrative Citations (Works Cited in Prose):

    • Citation elements are integrated directly into the syntax and phrasing of the sentence.
    • First Mention Rule: When an author is introduced for the first time in prose, use their full name (e.g., Naomi Baron).
    • Subsequent Mention Rule: For any subsequent references to that author in prose, use only their last name (e.g., Baron).
    • Page Number Placement: The page number inside parentheses is placed immediately following the first mention of the author's name in the prose sentence.

In-Text Citations for Single Authors and Co-Authors

  • Single Author:

    • Works Cited Entry Format: Author's last name, followed by first name.
    • Parenthetical Example: (Baron 193)
    • Prose Example (First Mention): Naomi Baron (193) demonstrates that…
    • Prose Example (Subsequent Mention): Baron further outlines that…

  • Two Co-Authors:

    • Works Cited Entry Format: First author listed as Last Name, First Name, joined by the word and, followed by second author as First Name Last Name (e.g., J. Lemmery and Paul Umberbatch).
    • Parenthetical Format: Include both authors' last names separated by the word and, followed by a single space and the page or page range: (Lemmery and Umberbatch 4-5).
    • Prose Format (First Mention): Write out both authors' full names separated by and: J. Lemmery and Paul Umberbatch (4-5) note that…
    • Prose Format (Subsequent Mention): Use only the last names of both authors: Lemmery and Umberbatch explain…

  • Three or More Authors:

    • Primary Author Designation: The author listed first in the original source is designated as the primary contributor and is listed first in citations.
    • Parenthetical Format: Use the first author's last name followed by et al. (Latin abbreviation for "and others"), a period after al., a space, and the page number: (Nickerson et al. 193).
    • Prose Format: In narrative prose, do not use the Latin abbreviation et al. Instead, write out the first author's full name (or last name on subsequent mention) followed by the phrase and colleagues (e.g., Raymond Nickerson and colleagues (193) argue… or Nickerson and colleagues state…).

Corporate Authors, Anonymous Works, and Non-Page Sources

  • Corporate / Group Authors:

    • Applies when a corporation, government agency, organization, or group is listed as the author (e.g., National Academy of Sciences and the Royal Society).
    • Parenthetical Format: Keep citations brief to avoid interrupting narrative flow. Use standard official abbreviations if appropriate, or shorten the organization's name to its shortest clear noun phrase (e.g., (National Academy 15)).
    • Prose Format: Write out the full name of the corporation/organization upon first mention. Shortened noun phrases may be used in subsequent narrative mentions.

  • Works with No Known Author:

    • General Rule: Match the in-text citation element to the first entry element of the corresponding Works Cited reference (which defaults to the title of the work).
    • Parenthetical Format: Shorten long titles to a concise noun phrase. Maintain the font styling used in the Works Cited entry (e.g., if the title is italicized on the Works Cited page, italicize it in the citation: (Reading at Risk 42) or shortened to (Reading 42)).
    • Prose Format: Incorporate the work's title into the narrative text using matching formatting (e.g., In Reading at Risk (42)…).

  • Sources Without Page Numbers:

    • General Rule: Substitute page numbers with an alternative numeric location marker provided by the source, preceded by an abbreviated label indicating the division type.
    • Common Location Labels:
    • sec. or sec for Section (e.g., (Author sec. 4))
    • ch. for Chapter (e.g., (Author ch. 2))
    • line for Line (e.g., (Author line 100))
    • para. for Paragraph (e.g., (Author para. 3))
    • Selection Criteria: Choose the locator label that most accurately guides the reader directly to the specific location of the cited material within the unpaginated source.
    • Hyphenated / Compound Last Names: Retain hyphenated or multi-word surnames exactly as they appear in the Works Cited entry.

Complex Scenarios: Same Surname and Multiple Works by Same Author

  • Two Authors with the Same Surname:

    • Applies when citing different authors who share the same last name (e.g., Jamie Baron and Naomi Baron).
    • Parenthetical Format: Distinguish between authors by including the first name's initial before the surname (e.g., (N. Baron 193) vs. (J. Baron 45)).
    • Prose Format: State the full name upon first mention (e.g., Naomi Baron). For all subsequent narrative mentions, use the author's full first name instead of the surname (e.g., using Naomi rather than Baron) to eliminate ambiguity.

  • Multiple Works by the Same Author:

    • Applies when citing two or more distinct sources written by the same individual author (e.g., Toni Morrison authoring both Beloved and Playing in the Dark).
    • Parenthetical Format: Combine three elements: Author's Last Name, followed by a comma, the italicized title (or shortened title noun phrase), a space, and the page number (e.g., (Morrison, Beloved 50)).
    • Prose Format Options:
    • Option 1 (Full Narrative Integration): Incorporate both the author's name and the specific work's title directly into the wording of the sentence, placing only the page number in parentheses at the end (e.g., Toni Morrison in Beloved demonstrates that… (50)).
    • Option 2 (Partial Narrative Integration): Include the author's name in the prose, while combining the italicized title and page number inside parentheses at the end of the sentence (e.g., Morrison demonstrates that… (Beloved 50)).
    • Name Conventions in Prose: State the author's full name (e.g., Toni Morrison) on first mention; use the surname (e.g., Morrison) on subsequent mentions.
