Skills to Develop
- Apply APA guidelines for citing sources within the body of the paper for various source types
Throughout the body of your paper, you must include a citation whenever you quote or paraphrase material from your research sources. The purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; you will provide more detailed information for each source you cite in text in the references section. (Refer to your JIBC APA Reference Guide for guidance on compose citation—for quotes or paraphrasing—under the referencing example for each type of source.)
In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, you must include the page number where the quote appears in the work being cited. This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.
Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).
Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.
Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).
Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.
As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”
Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that in this example the parenthetical citation is placed before the comma that signals the end of the introductory phrase.
David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).
Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can use the option that works best for that particular sentence and source.
Citing a book with a single author is usually straightforward. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews.
In each of the sentences below, identify the mistakes with how the quote was incorporated. Look carefully; some of them are tricky and have more than one error.
One researcher outlines the viewpoints of both parties:
Freedom of research is undoubtedly a cherished ideal in our society. In that respect, research has an interest in being free, independent, and unrestricted. Such interests weigh against regulations. On the other hand, research should also be valid, verifiable, and unbiased, to attain the overarching goal of gaining obtaining generalisable knowledge (Simonsen, 2012, p. 46).
According to a recent research study, ‘that women aged 41 and over were 5 times less likely to use condoms than were men aged 18 and younger’ (2007, p. 707).
According to Emlet, the rate in which older adults have contracted HIV has grown exponentially. Currently, “approximately 20% of all HIV cases were among older adults”. (Emlet, 2008).
Examples taken from:
Writing Commons. (2014, September). Open Text. Retrieved from http://writingcommons.org/format/apa...quotations-apa
The quote is not indented on either side.
[sic] is required after “obtaining”because it is a mistake in the original.
The period is placed after the citation not before.
“That” should have been removed to make the quote flow with the rest of the sentence.
There is no attributive tag and no mention of the authors in the citation: Sormanti & Shibusawa
Single quotation marks are used instead of double quotation marks.
The writer used an attributive tag with the name of the source’s author, then gave the name again in the citation at the end. The second one is redundant.
The original quote used the past tense (“were”), but the transition word “currently” requires this verb to be changed to present tense (“are”) inside square brackets to make it fit.
There is an extra period before the citation. With a short quote, you put the end punctuation after the citation.
Formatting In–Text Citations
The following subsections 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.
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 the JIBC APA Reference Guide. 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 should include an a after the year, the source listed second should include 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).
The author’s last name is again mentioned in the final citation despite it being used in the attributive tag. In this case, this is acceptable because this is referring to a different source written by the same person.
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. There is no period comes after et, but there is one with al. 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 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).
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).
In this example, 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.
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.).
For personal communications, such as interviews, letters, and emails, 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: 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 supervisor or 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 instructor what particular standards you should follow.
