Summarizing, Paraphrasing, and Quoting

Depending on the conventions of your discipline, you may have to decide whether to summarize a source, paraphrase a source, or quote from a source.

Scholars in the humanities tend to summarize, paraphrase, and quote texts; social scientists and natural scientists rely primarily on summary and paraphrase.

When and how to summarize

When you summarize, you provide your readers with a condensed version of an author's key points. A summary can be as short as a few sentences or much longer, depending on the complexity of the text and the level of detail you wish to provide to your readers. You will need to summarize a source in your paper when you are going to refer to that source and you want your readers to understand the source's argument, main ideas, or plot (if the source is a novel, film, or play) before you lay out your own argument about it, analysis of it, or response to it.

Before you summarize a source in your paper, you should decide what your reader needs to know about that source in order to understand your argument. For example, if you are making an argument about a novel, you should avoid filling pages of your paper with details from the book that will distract or confuse your reader. Instead, you should add details sparingly, going only into the depth that is necessary for your reader to understand and appreciate your argument. Similarly, if you are writing a paper about a journal article, you will need to highlight the most relevant parts of the argument for your reader, but you should not include all of the background information and examples. When you have to decide how much summary to put in a paper, it's a good idea to consult your instructor about whether you are supposed to assume your reader's knowledge of the sources.

Guidelines for summarizing a source in your paper

  • Identify the author and the source.
  • Represent the original source accurately.
  • Present the source’s central claim clearly.
  • Don’t summarize each point in the same order as the original source; focus on giving your reader the most important parts of the source
  • Use your own words. Don’t provide a long quotation in the summary unless the actual language from the source is going to be important for your reader to see.

Example

Stanley Milgram (1974) reports that ordinarily compassionate people will be cruel to each other if they are commanded to be by an authority figure. In his experiment, a group of participants were asked to administer electric shocks to people who made errors on a simple test. In spite of signs that those receiving shock were experiencing great physical pain, 25 of 40 subjects continued to administer electric shocks. These results held up for each group of people tested, no matter the demographic. The transcripts of conversations from the experiment reveal that although many of the participants felt increasingly uncomfortable, they continued to obey the experimenter, often showing great deference for the experimenter. Milgram suggests that when people feel responsible for carrying out the wishes of an authority figure, they do not feel responsible for the actual actions they are performing. He concludes that the increasing division of labor in society encourages people to focus on a small task and eschew responsibility for anything they do not directly control.

This summary of Stanley Milgram's 1974 essay, "The Perils of Obedience," provides a brief overview of Milgram's 12-page essay, along with an APA style parenthetical citation. You would write this type of summary if you were discussing Milgram's experiment in a paper in which you were not supposed to assume your reader's knowledge of the sources. Depending on your assignment, your summary might be even shorter.

When you include a summary of a paper in your essay, you must cite the source. If you were using APA style in your paper, you would include a parenthetical citation in the summary, and you would also include a full citation in your reference list at the end of your paper. For the essay by Stanley Milgram, your citation in your references list would include the following information:

When and how to paraphrase

When you paraphrase from a source, you restate the source's ideas in your own words. Whereas a summary provides your readers with a condensed overview of a source (or part of a source), a paraphrase of a source offers your readers the same level of detail provided in the original source. Therefore, while a summary will be shorter than the original source material, a paraphrase will generally be about the same length as the original source material.

When you use any part of a source in your paper—as background information, as evidence, as a counterargument to which you plan to respond, or in any other form—you will always need to decide whether to quote directly from the source or to paraphrase it. Unless you have a good reason to quote directly from the source, you should paraphrase the source. Any time you paraphrase an author's words and ideas in your paper, you should make it clear to your reader why you are presenting this particular material from a source at this point in your paper. You should also make sure you have represented the author accurately, that you have used your own words consistently, and that you have cited the source.

Example

This paraphrase below restates one of Milgram's points in the author's own words. When you paraphrase, you should always cite the source. This paraphrase uses the APA in-text citation style. Every source you paraphrase should also be included in your list of references at the end of your paper. For citation format information go to the Citing Sources section of this guide.

Source material

The problem of obedience is not wholly psychological. The form and shape of society and the way it is developing have much to do with it. There was a time, perhaps, when people were able to give a fully human response to any situation because they were fully absorbed in it as human beings. But as soon as there was a division of labor things changed.

--Stanley Milgram, "The Perils of Obedience," p.737.

Milgram, S. (1974). The perils of obedience. In L.G. Kirszner & S.R. Mandell (Eds.), The Blair reader (pp.725-737). Prentice Hall.

Paraphrase

Milgram (1974) claims that people's willingness to obey authority figures cannot be explained by psychological factors alone. In an earlier era, people may have had the ability to invest in social situations to a greater extent. However, as society has become increasingly structured by a division of labor, people have become more alienated from situations over which they do not have control (p.737).

When and how much to quote

The basic rule in all disciplines is that you should only quote directly from a text when it's important for your reader to see the actual language used by the author of the source. While paraphrase and summary are effective ways to introduce your reader to someone's ideas, quoting directly from a text allows you to introduce your reader to the way those ideas are expressed by showing such details as language, syntax, and cadence.

So, for example, it may be important for a reader to see a passage of text quoted directly from Tim O'Brien's The Things They Carried if you plan to analyze the language of that passage in order to support your thesis about the book. On the other hand, if you're writing a paper in which you're making a claim about the reading habits of American elementary school students or reviewing the current research on Wilson's disease, the information you’re providing from sources will often be more important than the exact words. In those cases, you should paraphrase rather than quoting directly. Whether you quote from your source or paraphrase it, be sure to provide a citation for your source, using the correct format. (see Citing Sources section)

You should use quotations in the following situations:

  • When you plan to discuss the actual language of a text.
  • When you are discussing an author's position or theory, and you plan to discuss the wording of a core assertion or kernel of the argument in your paper.
  • When you risk losing the essence of the author's ideas in the translation from their words to your own.
  • When you want to appeal to the authority of the author and using their words will emphasize that authority.

Once you have decided to quote part of a text, you'll need to decide whether you are going to quote a long passage (a block quotation) or a short passage (a sentence or two within the text of your essay). Unless you are planning to do something substantive with a long quotation—to analyze the language in detail or otherwise break it down—you should not use block quotations in your essay. While long quotations will stretch your page limit, they don't add anything to your argument unless you also spend time discussing them in a way that illuminates a point you're making. Unless you are giving your readers something they need to appreciate your argument, you should use quotations sparingly.

When you quote from a source, you should make sure to cite the source either with an in-text citation or a note, depending on which citation style you are using. The passage below, drawn from O’Brien’s The Things They Carried, uses an MLA-style citation.

Example

Source material

On the morning after Ted Lavender died, First Lieutenant Jimmy Cross crouched at the bottom of his foxhole and burned Martha's letters. Then he burned the two photographs. There was a steady rain falling, which made it difficult, but he used heat tabs and Sterno to build a small fire, screening it with his body holding the photographs over the tight blue flame with the tip of his fingers.

He realized it was only a gesture. Stupid, he thought. Sentimental, too, but mostly just stupid. (23)

O'Brien, Tim. The Things They Carried. New York: Broadway Books, 1990.

Quotation

Even as Jimmy Cross burns Martha's letters, he realizes that "it was only a gesture. Stupid, he thought. Sentimental too, but mostly just stupid" (23).

If you were writing a paper about O'Brien's The Things They Carried in which you analyzed Cross's decision to burn Martha's letters and stop thinking about her, you might want your reader to see the language O'Brien uses to illustrate Cross's inner conflict. If you were planning to analyze the passage in which O'Brien calls Cross's realization stupid, sentimental, and then stupid again, you would want your reader to see the original language.
