10.1: Citing and Referencing Techniques
- Apply American Psychological Association (APA) style formatting guidelines for citations.
This section covers the nitty-gritty details of in-text citations. You will learn how to format citations for different types of source materials, whether you are citing brief quotations, paraphrasing ideas, or quoting longer passages. You will also learn techniques you can use to introduce quoted and paraphrased material effectively. Keep this section handy as a reference to consult while writing the body of your paper.
Formatting Cited Material: The Basics
As noted in previous sections of this book, in-text citations usually provide the name of the author(s) and the year the source was published. For direct quotations, the page number must also be included. Use past-tense verbs when introducing a quote—“Smith found…” and not “Smith finds.…”
Formatting Brief Quotations
For brief quotations—fewer than forty words—use quotation marks to indicate where the quoted material begins and ends, and cite the name of the author(s), the year of publication, and the page number where the quotation appears in your source. Remember to include commas to separate elements within the parenthetical citation. Also, avoid redundancy. If you name the author(s) in your sentence, do not repeat the name(s) in your parenthetical citation. Review following the examples of different ways to cite direct quotations.
Chang (2008) emphasized that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (p. 49).
The author’s name can be included in the body of the sentence or in the parenthetical citation. Note that when a parenthetical citation appears at the end of the sentence, it comes after the closing quotation marks and before the period. The elements within parentheses are separated by commas.
Weight Training for Women (Chang, 2008) claimed that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (p. 49).
Weight Training for Women claimed that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (Chang, 2008, p. 49).
Including the title of a source is optional.
In Chang’s 2008 text Weight Training for Women , she asserts, “Engaging in weight-bearing exercise is one of the single best things women can do to maintain good health” (p. 49).
The author’s name, the date, and the title may appear in the body of the text. Include the page number in the parenthetical citation. Also, notice the use of the verb asserts to introduce the direct quotation.
“Engaging in weight-bearing exercise,” Chang asserts, “is one of the single best things women can do to maintain good health” (2008, p. 49).
You may begin a sentence with the direct quotation and add the author’s name and a strong verb before continuing the quotation.
Formatting Paraphrased and Summarized Material
When you paraphrase or summarize ideas from a source, you follow the same guidelines previously provided, except that you are not required to provide the page number where the ideas are located. If you are summing up the main findings of a research article, simply providing the author’s name and publication year may suffice, but if you are paraphrasing a more specific idea, consider including the page number.
Read the following examples.
Chang (2008) pointed out that weight-bearing exercise has many potential benefits for women.
Here, the writer is summarizing a major idea that recurs throughout the source material. No page reference is needed.
Chang (2008) found that weight-bearing exercise could help women maintain or even increase bone density through middle age and beyond, reducing the likelihood that they will develop osteoporosis in later life (p. 86).
Although the writer is not directly quoting the source, this passage paraphrases a specific detail, so the writer chose to include the page number where the information is located.
Although APA style guidelines do not require writers to provide page numbers for material that is not directly quoted, your instructor may wish you to do so when possible.
Check with your instructor about his or her preferences.
Formatting Longer Quotations
When you quote a longer passage from a source—forty words or more—use a different format to set off the quoted material. Instead of using quotation marks, create a block quotation by starting the quotation on a new line and indented five spaces from the margin. Note that in this case, the parenthetical citation comes after the period that ends the sentence. Here is an example:
In recent years, many writers within the fitness industry have emphasized the ways in which women can benefit from weight-bearing exercise, such as weightlifting, karate, dancing, stair climbing, hiking, and jogging. Chang (2008) found that engaging in weight-bearing exercise regularly significantly reduces women’s risk of developing osteoporosis. Additionally, these exercises help women maintain muscle mass and overall strength, and many common forms of weight-bearing exercise, such as brisk walking or stair climbing, also provide noticeable cardiovascular benefits. (p. 93)
If you are quoting a passage that continues into a second paragraph, indent five spaces again in the first line of the second paragraph. Here is an example:
In recent years, many writers within the fitness industry have emphasized the ways in which women can benefit from weight-bearing exercise, such as weightlifting, karate, dancing, stair climbing, hiking, and jogging. Chang (2008) found that engaging in weight-bearing exercise regularly significantly reduces women’s risk of developing osteoporosis. Additionally, these exercises help women maintain muscle mass and overall strength, and many common forms of weight-bearing exercise, such as brisk walking or stair climbing, also provide noticeable cardiovascular benefits.
It is important to note that swimming cannot be considered a weight-bearing exercise, since the water supports and cushions the swimmer. That doesn’t mean swimming isn’t great exercise, but it should be considered one part of an integrated fitness program. (p. 93)
Be wary of quoting from sources at length. Remember, your ideas should drive the paper, and quotations should be used to support and enhance your points. Make sure any lengthy quotations that you include serve a clear purpose. Generally, no more than 10–15 percent of a paper should consist of quoted material.
Introducing Cited Material Effectively
Including an introductory phrase in your text, such as “Jackson wrote” or “Copeland found,” often helps you integrate source material smoothly. This citation technique also helps convey that you are actively engaged with your source material. Unfortunately, during the process of writing your research paper, it is easy to fall into a rut and use the same few dull verbs repeatedly, such as “Jones said,” “Smith stated,” and so on.
Punch up your writing by using strong verbs that help your reader understand how the source material presents ideas. There is a world of difference between an author who “suggests” and one who “claims,” one who “questions” and one who “criticizes.” You do not need to consult your thesaurus every time you cite a source, but do think about which verbs will accurately represent the ideas and make your writing more engaging. The following chart shows some possibilities.
| Strong Verbs for Introducing Cited Material | ||
|---|---|---|
| ask | suggest | question |
| explain | assert | claim |
| recommend | compare | contrast |
| propose | hypothesize | believe |
| insist | argue | find |
| determine | measure | assess |
| evaluate | conclude | study |
| warn | point out | sum up |
Writing at Work
It is important to accurately represent a colleague’s ideas or communications in the workplace. When writing professional or academic papers, be mindful of how the words you use to describe someone’s tone or ideas carry certain connotations. Do not say a source argues a particular point unless an argument is, in fact, presented. Use lively language, but avoid language that is emotionally charged. Doing so will ensure you have represented your colleague’s words in an authentic and accurate way.
Formatting In-Text Citations for Other Source Types
These sections discuss the correct format for various types of in-text citations. Read them through quickly to get a sense of what is covered, and then refer to them again as needed.
Print Sources
This section covers books, articles, and other print sources with one or more authors.
A Work by One Author
For a print work with one author, follow the guidelines provided in “Formatting a Research Paper.” Always include the author’s name and year of publication. Include a page reference whenever you quote a source directly. (See also the guidelines presented earlier in this chapter about when to include a page reference for paraphrased material.)
Chang (2008) emphasized that “engaging in weight-bearing exercise consistently is one of the single best things women can do to maintain good health” (p. 49).
Chang (2008) pointed out that weight-bearing exercise has many potential benefits for women.
Two or More Works by the Same Author
At times, your research may include multiple works by the same author. If the works were published in different years, a standard in-text citation will serve to distinguish them. If you are citing multiple works by the same author published in the same year, include a lowercase letter immediately after the year. Rank the sources in the order they appear in your references section. The source listed first includes an a after the year, the source listed second includes a b , and so on.
Rodriguez (2009a) criticized the nutrition-supplement industry for making unsubstantiated and sometimes misleading claims about the benefits of taking supplements. Additionally, he warned that consumers frequently do not realize the potential harmful effects of some popular supplements (Rodriguez, 2009b).
If you have not yet created your references section, you may not be sure which source will appear first. See “Creating a References Section” for guidelines—or assign each source a temporary code and highlight the in-text citations so you remember to double-check them later on.
Works by Authors with the Same Last Name
If you are citing works by different authors with the same last name, include each author’s initials in your citation, whether you mention them in the text or in parentheses. Do so even if the publication years are different.
J. S. Williams (2007) believes nutritional supplements can be a useful part of some diet and fitness regimens. C. D. Williams (2008), however, believes these supplements are overrated.
According to two leading researchers, the rate of childhood obesity exceeds the rate of adult obesity (K. Connelley, 2010; O. Connelley, 2010).
Studies from both A. Wright (2007) and C. A. Wright (2008) confirm the benefits of diet and exercise on weight loss.
A Work by Two Authors
When two authors are listed for a given work, include both authors’ names each time you cite the work. If you are citing their names in parentheses, use an ampersand (&) between them. (Use the word and , however, if the names appear in your sentence.)
As Garrison and Gould (2010) pointed out, “It is never too late to quit smoking. The health risks associated with this habit begin to decrease soon after a smoker quits” (p. 101).
As doctors continue to point out, “It is never too late to quit smoking. The health risks associated with this habit begin to decrease soon after a smoker quits” (Garrison & Gould, 2010, p. 101).
A Work by Three to Five Authors
If the work you are citing has three to five authors, list all the authors’ names the first time you cite the source. In subsequent citations, use the first author’s name followed by the abbreviation et al. ( Et al. is short for et alia , the Latin phrase for “and others.”)
Henderson, Davidian, and Degler (2010) surveyed 350 smokers aged 18 to 30.
One survey, conducted among 350 smokers aged 18 to 30, included a detailed questionnaire about participants’ motivations for smoking (Henderson, Davidian, & Degler, 2010).
Note that these examples follow the same ampersand conventions as sources with two authors. Again, use the ampersand only when listing authors’ names in parentheses.
As Henderson et al. (2010) found, some young people, particularly young women, use smoking as a means of appetite suppression.
Disturbingly, some young women use smoking as a means of appetite suppression (Henderson et al., 2010).
Note how the phrase et al. is punctuated. No period comes after et , but al. gets a period because it is an abbreviation for a longer Latin word. In parenthetical references, include a comma after et al. but not before. Remember this rule by mentally translating the citation to English: “Henderson and others, 2010.”
A Work by Six or More Authors
If the work you are citing has six or more authors, list only the first author’s name, followed by et al. , in your in-text citations. The other authors’ names will be listed in your references section.
Researchers have found that outreach work with young people has helped reduce tobacco use in some communities (Costello et al., 2007).
A Work Authored by an Organization
When citing a work that has no individual author(s) but is published by an organization, use the organization’s name in place of the author’s name. Lengthy organization names with well-known abbreviations can be abbreviated. In your first citation, use the full name, followed by the abbreviation in square brackets. Subsequent citations may use the abbreviation only.
It is possible for a patient to have a small stroke without even realizing it (American Heart Association [AHA], 2010).
Another cause for concern is that even if patients realize that they have had a stroke and need medical attention, they may not know which nearby facilities are best equipped to treat them (AHA, 2010).
A Work with No Listed Author
If no author is listed and the source cannot be attributed to an organization, use the title in place of the author’s name. You may use the full title in your sentence or use the first few words—enough to convey the key ideas—in a parenthetical reference. Follow standard conventions for using italics or quotations marks with titles:
- Use italics for titles of books or reports.
- Use quotation marks for titles of articles or chapters.
“Living With Diabetes: Managing Your Health” (2009) recommends regular exercise for patients with diabetes.
Regular exercise can benefit patients with diabetes (“Living with Diabetes,” 2009).
Rosenhan (1973) had mentally healthy study participants claim to be experiencing hallucinations so they would be admitted to psychiatric hospitals.
A Work Cited within Another Work
To cite a source that is referred to within another secondary source, name the first source in your sentence. Then, in parentheses, use the phrase as cited in and the name of the second source author.
Rosenhan’s study “On Being Sane in Insane Places” (as cited in Spitzer, 1975) found that psychiatrists diagnosed schizophrenia in people who claimed to be experiencing hallucinations and sought treatment—even though these patients were, in fact, imposters.
Two or More Works Cited in One Reference
At times, you may provide more than one citation in a parenthetical reference, such as when you are discussing related works or studies with similar results. List the citations in the same order they appear in your references section, and separate the citations with a semicolon.
Some researchers have found serious flaws in the way Rosenhan’s study was conducted (Dawes, 2001; Spitzer, 1975).
Both of these researchers authored works that support the point being made in this sentence, so it makes sense to include both in the same citation.
A Famous Text Published in Multiple Editions
In some cases, you may need to cite an extremely well-known work that has been repeatedly republished or translated. Many works of literature and sacred texts, as well as some classic nonfiction texts, fall into this category. For these works, the original date of publication may be unavailable. If so, include the year of publication or translation for your edition. Refer to specific parts or chapters if you need to cite a specific section. Discuss with your instructor whether he or she would like you to cite page numbers in this particular instance.
In New Introductory Lectures on Psycho-Analysis , Freud explains that the “manifest content” of a dream—what literally takes place—is separate from its “latent content,” or hidden meaning (trans. 1965, lecture XXIX).
Here, the student is citing a classic work of psychology, originally written in German and later translated to English. Since the book is a collection of Freud’s lectures, the student cites the lecture number rather than a page number.
An Introduction, Foreword, Preface, or Afterword
To cite an introduction, foreword, preface, or afterword, cite the author of the material and the year, following the same format used for other print materials.
Electronic Sources
Whenever possible, cite electronic sources as you would print sources, using the author, the date, and where appropriate, a page number. For some types of electronic sources—for instance, many online articles—this information is easily available. Other times, however, you will need to vary the format to reflect the differences in online media.
Online Sources without Page Numbers
If an online source has no page numbers but you want to refer to a specific portion of the source, try to locate other information you can use to direct your reader to the information cited. Some websites number paragraphs within published articles; if so, include the paragraph number in your citation. Precede the paragraph number with the abbreviation for the word paragraph and the number of the paragraph (e.g., para. 4).
As researchers have explained, “Incorporating fresh fruits and vegetables into one’s diet can be a challenge for residents of areas where there are few or no easily accessible supermarkets” (Smith & Jones, 2006, para. 4).
Even if a source does not have numbered paragraphs, it is likely to have headings that organize the content. In your citation, name the section where your cited information appears, followed by a paragraph number.
The American Lung Association (2010) noted, “After smoking, radon exposure is the second most common cause of lung cancer” (What Causes Lung Cancer? section, para. 2).
This student cited the appropriate section heading within the website and then counted to find the specific paragraph where the cited information was located.
If an online source has no listed author and no date, use the source title and the abbreviation n.d. in your parenthetical reference.
It has been suggested that electromagnetic radiation from cellular telephones may pose a risk for developing certain cancers (“Cell Phones and Cancer,” n.d.).
Personal Communication
For personal communications, such as interviews, letters, and e-mails, cite the name of the person involved, clarify that the material is from a personal communication, and provide the specific date the communication took place. Note that while in-text citations correspond to entries in the references section, personal communications are an exception to this rule. They are cited only in the body text of your paper.
J. H. Yardley, M.D., believes that available information on the relationship between cell phone use and cancer is inconclusive (personal communication, May 1, 2009).
Writing at Work
At work, you may sometimes share information resources with your colleagues by photocopying an interesting article or forwarding the URL of a useful website. Your goal in these situations and in formal research citations is the same. The goal is to provide enough information to help your professional peers locate and follow up on potentially useful information. Provide as much specific information as possible to achieve that goal, and consult with your professor as to what specific style he or she may prefer.
- In APA papers, in-text citations include the name of the author(s) and the year of publication whenever possible.
- Page numbers are always included when citing quotations. It is optional to include page numbers when citing paraphrased material; however, this should be done when citing a specific portion of a work.
- When citing online sources, provide the same information used for print sources if it is available.
- When a source does not provide information that usually appears in a citation, in-text citations should provide readers with alternative information that would help them locate the source material. This may include the title of the source, section headings and paragraph numbers for websites, and so forth.
- When writing a paper, discuss with your professor what particular standards he or she would like you to follow.
1. Review the places in your paper where you cited, quoted, and paraphrased material from a source with a single author. Edit your citations to ensure that
- each citation includes the author’s name, the date of publication, and, where appropriate, a page reference;
- parenthetical citations are correctly formatted;
- longer quotations use the block-quotation format.
2. Review the citations in your paper once again. This time, look for places where you introduced source material using a signal phrase in your sentence.
- Highlight the verbs used in your signal phrases, and make note of any that seem to be overused throughout the paper.
- Identify at least three places where a stronger verb could be used.
- Make the edits to your draft.
3. Review the places in your paper where you cited material from a source with multiple authors or with an organization as the author. Edit your citations to ensure that each citation follows APA guidelines for the inclusion of the authors’ names, the use of ampersands and et al. , the date of publication, and, where appropriate, a page reference.
