Citing Sources and Plagiarism

The most common way to cite sources is to use a bibliography or "Works Cited" list at the end of your paper. The works cited list includes a citation for each of the sources you used to write your paper. The citations are formatted in a consistent style according to one of several standard citation formats. The two most common citation formats for college research papers are: (1) The APA Publication Manual (American Psychological Association) - predominately used in Social Sciences and (2) The MLA Handbook (Modern Language Association) - predominately used in Humanities and Liberal Arts. A third citation format is CMS Handbook (Chicago Manual of Style) and is used primarily in History, but also in Humanities and Social Sciences. Copies of the MLA Handbook (LB 2369 M52 2021), the APA Manual (BF76.7 .P83 2020), and the CMS Handbook (Z253 .U69 2017) are available in the Library stacks and the reference collection. Assistance with writing your paper is available at the VVC Writing Center. Always check with your instructor for the required citation format.

APA Citation

Publication Manual ImageSource: American Psychological Association. (2020). Publication Manual of the American Psychological Association (7th ed.). Washington, DC: Author.

The APA (American Psychological Association) style is most widely used for college research papers in the social and behavioral sciences. There are two parts to creating a citation in the APA format. The first part consists of an "In-text citation" noting the author's name and page number in parentheses for each source used in writing your paper. The second part is a “References” list at the end of the paper that includes a citation for each source used in the in-text citations. The citations are arranged in alphabetical order and written in a standardized format for both print and online sources.

  • Additional information regarding why and when to cite sources can be found under "Understanding Plagiarism." The VVC Writing Center is also available to assist you with questions relating to writing papers, essays, and more.
  • Check out the APA style website for additional guidance. 
  • The examples listed on the separate tabs above were created by VVC librarians and are based on the 7th ed. of the APA Manual. These examples represent some of the most often used resources found in the VVC library. For further examples, please refer to copies of the manual located in the library stacks and reference collection (BF76.7 .P83 2020).

Caution: Depending on the screen size of your computer or device, the formatting in the examples may not display correctly. Note that all citations should be double-spaced and indented five spaces after the first line.

Citing Online Articles in APA

 Since online materials can potentially change URL's, APA recommends providing a Digital Object Identifier (DOI), when it is available. DOI's are an attempt to provide stable links for online articles. They are unique to their documents and consist of a long alphanumeric code. Do not include database information for works obtained from most academic research databases or platforms because works in these resources are widely available. This includes journal articles, books, and book chapters from academic research databases. (9.34 page 299) Students should check with their instructor regarding citation requirements and formats.

  • Use the DOI number when provided for sources found on the Internet.
    Example:  doi:10.1542/peds.2007-2361

  • For works without DOIs from most academic research databases, do not include a URL or database information in the reference because these works are widely available.
  • Use the URL for articles without a DOI and all other Internet sources.

How Can You Avoid Plagiarism?

To avoid plagiarism you need to recognize when credit is due. Types of plagiarism include direct copying, paraphrasing, and using another person's idea, opinion, or theory. Take a look at the table below:

You Must Give Credit When Using: Credit Is Not Needed When Using:
  • Summaries, paraphrases, or direct quotations from a source
  • Reprints of diagrams, charts, illustrations, or pictures Little-known facts
  • Other people's opinions
  • Results of other people's research (opinion polls, case studies, statistics, etc.)
  • Quotations or paraphrases from people you interview
  • Common knowledge (facts that can be found in many places and are likely to be known by many people)
  • Your own ideas, opinions, experiences, and conclusions
  • Your own research (surveys or observations)

Examples of Plagiarism

Example One: Paraphrasing from the original source

Original Text
(from Democracy in America By Brian P. Janiskee and Ken Masugi , 2003)
The influence of the entertainment industry on state politics is limited. Because the federal government has jurisdiction over the entertainment industry via the Federal Communications Commission, most of the entertainment industry’s lobbying efforts focus on federal issues. Also, many Hollywood stars parlay their high visibility into elected office or positions of political influence.
Unacceptable Paraphrase
The power of the entertainment industry on state and local politics is inadequate. The reason why is that the federal government has jurisdiction over the entertainment industry through the FCC, most of the entertainment industry’s lobbying efforts look at federal issues. Also, many Hollywood actors use their fame to move into elected offices or influence politicians.
Why is it Plagiarism?
  1. Only a few words were changed or the order of words was altered.
  2. The source of the text is not cited at the end.
Acceptable Paraphrase The influence the entertainment industry has on state politics is narrow. The entertainment industry however tends to have more of an impact on federal issues due to the fact that the entertainment industry has oversight from the Federal Communications Commission. "Hollywood stars parlay their high visibility into elected office or positions of political influence. The late Sonny Bono became mayor of Palm Springs and then was elected to Congress" (Janiskee 36).
Why is it Acceptable?
  1. The passage was rewritten in the writer's own words while maintaining the meaning of the original text.
  2. The source of the text is cited at the end.
Note: You can use paraphrase and quotations together. This is particularly useful for phrases that you do not wish to reword because it may alter the meaning.

Example Two:
Quoting from the original source

Original Text
(from Conservatism an Anthology of Social and Political Thought from David Hume to the Present by Jerry Z. Miller, 1997).
Both American liberals and conservatives in the 1960s embraced the notion of a “culture of poverty,” a phrase coined by the anthropologist Oscar Lewis. To liberals, the concept suggested that the culture of the poor, which limited their upward social mobility, could be transformed by government agencies such as schools, enrichment programs for pre-school children, and job training programs.
Unacceptable Quote
"Both American liberals and conservatives in the 1960s embraced the notion of a culture of the poor. To the liberals, the concept suggested that the poor, who had limited social mobility, could rely on government programs to transform their social class."
Why is it Plagiarism?
  1. The passage has not been quoted accurately.
  2. The source of the quotation is not cited at the end.
Acceptable Quotation It is believed that American liberals during the 1960s embraced the phrase a "culture of poverty." "To liberals, the concept suggested that the culture of the poor, which limited their upward social mobility, could be transformed by government agencies such as schools, enrichment programs for pre-school children, and job training programs" (Miller 336).
Why is it Acceptable?
  1. The first sentence is an acceptable paraphrase.
  2. The second sentence is quoted accurately.
  3. The whole passage is cited.

Note: VVC Students should be aware that plagiarism violates the proscribed student conduct code and may result in possible consequences as stated in the VVC Student Handbook (p.38 D).
