Why Citations?

When using outside sources or others’ ideas to strengthen an argument in your paper, you must give the author(s) credit to avoid any charges of plagiarism (see John Jay College’s policy on Academic Integrity).

MLA (Modern Language Association) is one style of formatting citations for outside sources for BOTH your Works Cited page (list of your sources at the end of your paper) and in-text citations (references, within the body of your paper, to a source you have listed on your Works Cited page).

This guide provides citation examples to the most common sources.  Use the tabs on the left for help with formatting your paper, citing different types of source and creating in-text citations.

If you need more guidance, contact your instructor, a Lloyd Sealy librarian or the John Jay Writing Center.

Quoting, Paraphrasing and Summarizing

Quoting, paraphrasing and summarizing are three ways to incorporate outside sources into your paper. When incorporating external sources in the body of your paper you must include in-text citations that gives credit to those sources. In-text citations refer the reader to the source's listing in your Works Cited page.  

It, therefore, helps to complete your References page listing all your sources first.

Quoting

Quoting is reproducing text verbatim (exactly as written) from another source. You must include an in-text or parenthetical citation for direct quotes that gives credit to the author/source AND refers the reader to that source which is listed on your Works Cited page so they may find that source and the quote you've included. 

There are 2 kinds of in-text citations:

(a) Short Quotations (no more than 4 lines in your paper): Incorporate the quote into the narrative of your text using quotation marks. MLA does not require the year of the publication you are citing.  Place the citation in parentheses without any punctuation inside.

When mentioning an author by name: add the page number where the quote can be found either after the author's name or at the end of the sentence after the end quotation mark and before the period:

According to Geppert (116), "it is imperative that development economists extend their research beyond purely economic factors and focus their attention on creating more inclusive, and hence more accurate, measures of development and national well-being." 

According to Geppert, "it is imperative that development economists extend their research beyond purely economic factors and focus their attention on creating more inclusive, and hence more accurate, measures of development and national well-being" (116).

Quote without mentioning an author by name: provide the author's name and page number within parentheses without any punctuation before the period:

According to some, "it is imperative that development economists extend their research beyond purely economic factors and focus their attention on creating more inclusive, and hence more accurate, measures of development and national well-being" (Geppert 116).

When your work has no author (Works Cited entry begins with the title of the work) provide a shortened version of the title beginning with the first word, ignoring initial articles such as the, an, a.

In ancient Egypt, black pigment “was the best-known form of makeup…used by people of all classes” (Egyptian 39).

When the author has more than one work in your Works Cited page, add a shortened version of the title (NOT date) to distinguish the work.

We must remember that "culture is public because meaning is" (Geertz Interpretation 12).

(b) Long or Block Quotations (quote that runs more than 4 lines in your paper): Separate the quote by creating a double-spaced indented block without quotation marks. Indent 5 spaces from the left margin. Place the in-text citation in parentheses after the author's name or at the end of the quote:

As Clifford Geertz reminds us:

From one point of view, that of the textbook, doing ethnography is establishing rapport, selecting informants, transcribing texts, taking genealogies, mapping fields, keeping a diary, and so on. But it is not these things, techniques and received procedures, that define the enterprise. What defines it is the kind of intellectual effort it is: an elaborate venture in, to borrow a notion from Gilbert Ryle, “thick description” (Interpretation 6).

 

Paraphrasing and Summarizing

Paraphrasing is using your own words to present someone else's idea(s). Summarizing is stating the essence of another's idea(s). You need an in-text citation each time you paraphrase or summarize another's idea.  The citation refers the reader to that source listed on your Works Cited page and may include the specific page, chapter, section, etc. of the source being discussed.

Use quotation marks for original words or phrases that come directly from the author or source.

According to Zapf & Jung, “criminal responsibility” can be evaluated by referring to information from the defendant’s interview and forensic test results (340).
