Examples Of Work Cited Pages For Essays On Global Warming

MLA (Modern Language Association) is the most common form of citation used within the liberal arts and humanities. This guide provides examples for the general format of MLA research papers using in-text citations and a Works Cited page.

Quoting the Text Directly

In-Text Citation Example
      “Officers on bikes are more accessible to residents than those riding in cars and can often
      respond quicker and sneak up on criminals without fanfare” (Hermann).

Note: Publications that originate on the Web often don’t have page numbers, so don’t worry about including them in your parenthetical reference.

Works Cited Example
Last, First M. "Article Title." Newspaper Title Date Month Year Published: Page(s). Website Title.
      Web. Date Month Year Accessed.

Hermann, Peter. “D.C. Police Hit the Streets on New Mountain Bikes — with Sirens.” The
      Washington Post. 20 Oct. 2015. Web. 21 Oct. 2015.

Note: This includes the date that the article was originally published, and the day that it was referenced for the research for which it is being used.

Referencing Specific Information

When you reference a specific fact or idea in your paper, even if it is not a direct quote, you will add a parentheses at the end of the sentence that includes the author of your source and the page number you found it on (the page number is not needed if it is an online source). The period for the sentence comes after the citation.

In-Text Citation Example
      Although climate change will cause irreversible harm to food production and human
      health, a new United Nations report shows that world governments are not prepared for
      the worst of the changes (Howard).

Works Cited Example
Howard, Brian Clark. “New Climate Change Report Warns of Dire Consequences.” National
      Geographic. 31 March 2014. Web. 14 July 2015.

Note: MLA no longer requires you to include the URL in a citation, but if you would like to, you can include the URL at the end of your citation

No Author?

When your source does not have an author, it is okay to cite a shortened version of the article title in quotes (or, in the case of a longer form work like a book, the title in italics).

In-Text Citation Example
      If we do not begin cutting back on carbon dioxide emissions within the next five years,
      global warming could become unstoppable by 2042 (“Point of No Return”).

Works Cited Example
“Have We Passed the Point of No Return on Climate Change?” EarthTalk. Scientific American,
      13 April 2015. Web. 13 July 2015.

Newsela articles

Like the one above, these articles should be cited using the following format:

Original author’s last name, author’s first name, original publication via Newsela (Ed. Newsela
      Lexile #). “Headline of Newsela Version of Article.” Date published. Web. Date Accessed.

Works Cited Example
Susman, Tina, Los Angeles Times via Newsela (Ed. Newsela staff. Version 1110). “Bracing for
      a New Civil Rights Movement.” 12 August 2014. Web. 22 July 2015.

Find that article here.

Notice that the Lexile # is the number that is highlighted in the blue rectangle on the right side of the page. You can find the original author of the article by clicking the blue “MAX” button on the right side of the article, above the highlighted number, and checking the byline.

Introducing Evidence

It can be a good idea to introduce a piece of evidence with the name of the source, rather than waiting to put the source at the end of the sentence. If the sentence makes it clear who the author of the work is, the in-text citation should only include the page number.

In-Text Citation Example
      Rich Lowry argues that voter identification laws have no impact on voter turnout (3).

Works Cited Example
Lowry, Rich. “The Poll Tax That Wasn’t.” Politico Magazine. Politico, 22 October 2014. Web. 6
      July 2015.

Citing a Source that Cites Someone Else

If you are citing a part of your source that quotes someone else, that must be made clear in your in-text citation.

In-Text Citation Example
      Yet Pat Mullins says that “even one instance of voter fraud is too many” (qtd. in
      Badger 2).

Works Cited Example
Badger, Emily. “Why Arguments for Voter ID Laws Don’t Add Up.” Washington Post
      24 October 2014: Web. 19 July 2015.

FAQ about MLA Basics

1) How do I know what to cite?
Any source that is referenced in an in-text citation must appear in your Works Cited list. Your Works Cited list may also include sources that do not have specific in-text citations but that helped you with your paper in other ways, such as providing background information.

2) What if the source doesn’t provide information MLA requires?
If MLA asks for specific information that your source doesn’t have, you should denote that through the following abbreviations:
n.p. - no publisher’s name provided
n.d. - no date provided
n. pag. - no page number provided

3) How do I create my Works Cited page?
Works Cited should come at the end of your research, on a separate page. At the top, center you want to label it “Works Cited.” Then, each source is listed alphabetically. The citations should also be double spaced.

MLA In-Text Citations: The Basics


MLA (Modern Language Association) style is most commonly used to write papers and cite sources within the liberal arts and humanities. This resource, updated to reflect the MLA Handbook (8th ed.), offers examples for the general format of MLA research papers, in-text citations, endnotes/footnotes, and the Works Cited page.

Guidelines for referring to the works of others in your text using MLA style are covered in chapter 6 of the MLA Handbook and in chapter 7 of the MLA Style Manual. Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA style, referring to the works of others in your text is done by using what is known as parenthetical citation. This method involves placing relevant source information in parentheses after a quote or a paraphrase.

General Guidelines

  • The source information required in a parenthetical citation depends (1.) upon the source medium (e.g. Print, Web, DVD) and (2.) upon the source’s entry on the Works Cited (bibliography) page.
  • Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text, must be the first thing that appears on the left-hand margin of the corresponding entry in the Works Cited List.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Wordsworth stated that Romantic poetry was marked by a "spontaneous overflow of powerful feelings" (263).

Romantic poetry is characterized by the "spontaneous overflow of powerful feelings" (Wordsworth 263).

Wordsworth extensively explored the role of emotion in the creative process (263).

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads. Oxford UP, 1967.

In-text citations for print sources with known author

For Print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

Human beings have been described by Kenneth Burke as "symbol-using animals" (3).

Human beings have been described as "symbol-using animals" (Burke 3).

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry in the Works Cited:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method. Berkeley: U of California P, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name. Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

We see so many global warming hotspots in North America likely because this region has "more readily accessible climatic data and more comprehensive programs to monitor and study environmental change . . ." ("Impact of Global Warming").

In this example, since the reader does not know the author of the article, an abbreviated title of the article appears in the parenthetical citation which corresponds to the full name of the article which appears first at the left-hand margin of its respective entry in the Works Cited. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs. 1999. http://www.climatehotmap.org/. Accessed 23 Mar. 2009.

We'll learn how to make a Works Cited page in a bit, but right now it's important to know that parenthetical citations and Works Cited pages allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work like Marx and Engels's The Communist Manifesto. In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Marx and Engels described human history as marked by class struggles (79; ch. 1).

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Although some medical ethicists claim that cloning will lead to designer children (R. Miller 12), others note that the advantages for medical research outweigh this consideration (A. Miller 46).

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Best and Marcus argue that one should read a text for what it says on its surface, rather than looking for some hidden meaning (9).

The authors claim that surface reading looks at what is “evident, perceptible, apprehensible in texts” (Best and Marcus 9).

Corresponding works cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations, vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

According to Franck et al., “Current agricultural policies in the U.S. are contributing to the poor health of Americans” (327).

The authors claim that one cause of obesity in the United States is government-funded farm subsidies (Franck et al. 327).

Corresponding works cited entry:

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine, vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by a particular author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author:

Lightenor has argued that computers are not useful tools for small children ("Too Soon" 38), though he has acknowledged elsewhere that early exposure to computer games does lead to better small motor skill development in a child's second and third year ("Hand-Eye Development" 17).

Citing two books by the same author:

Murray states that writing is "a process" that "varies with our thinking style" (Write to Learn 6). Additionally, Murray argues that the purpose of writing is to "carry ideas and information from the mind of one person into the mind of another" (A Writer Teaches Writing 3).

Additionally, if the author's name is not mentioned in the sentence, you would format your citation with the author's name followed by a comma, followed by a shortened title of the work, followed, when appropriate, by page numbers:

Visual studies, because it is such a new discipline, may be "too easy" (Elkins, "Visual Studies" 63).

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

. . . as Quintilian wrote in Institutio Oratoria (1: 14-17).

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter and verse. For example:

Ezekiel saw "what seemed to be four living creatures," each with faces of a man, a lion, an ox, and an eagle (New Jerusalem Bible, Ezek. 1.5-10).

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation.

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited in another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Ravitch argues that high schools are pressured to act as "social service centers, and they don't do that well" (qtd. in Weisman 259).

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing non-print or sources from the Internet

With more and more scholarly work being posted on the Internet, you may have to cite research you have completed in virtual environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's Evaluating Sources of Information resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source in your Works Cited.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers, but often, these sorts of entries do not require any sort of parenthetical citation at all. For electronic and Internet sources, follow the following guidelines:

  • Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
  • You do not need to give paragraph numbers or page numbers based on your Web browser’s print preview function.
  • Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like CNN.com or Forbes.com as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Werner Herzog's Fitzcarraldo stars Herzog's long-time film partner, Klaus Kinski. During the shooting of Fitzcarraldo, Herzog and Kinski were often at odds, but their explosive relationship fostered a memorable and influential film.

During the presentation, Jane Yates stated that invention and pre-writing are areas of rhetoric that need more attention.

In the two examples above “Herzog” from the first entry and “Yates” from the second lead the reader to the first item each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo. Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002.

Electronic sources

One online film critic stated that Fitzcarraldo "has become notorious for its near-failure and many obstacles" (Taylor, “Fitzcarraldo”).

The Purdue OWL is accessed by millions of users every year. Its "MLA Formatting and Style Guide" is one of the most popular resources (Russell et al.).

In the first example, the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below). In the second example, “Russell et al.” in the parenthetical citation gives the reader an author name followed by the abbreviation “et al.,” meaning, “and others,” for the article “MLA Formatting and Style Guide.” Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant, 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/.

Russell, Tony, et al. "MLA Formatting and Style Guide." The Purdue OWL, 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

. . . as has been discussed elsewhere (Burke 3; Dewey 21).

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference, like so (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations or common knowledge. Remember, this is a rhetorical choice, based on audience. If you're writing for an expert audience of a scholarly journal, for example, they'll have different expectations of what constitutes common knowledge.
