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.
