CITING A WORK IN-TEXT

Three components are required:

Author (last name only), year of publication, page number (if applicable*).

*Include a page number if you're directly quoting a work or discussing an observation from the work, but if you're speaking more generally about the gist of the work, page numbers are not needed.

For short quotations or paraphrases, works can be cited in-text in two ways, always within the sentence (that is, before the period):

• Using the author's name in the text itself, known as a "signal phrase":

  • "Orlofsky discovered the powerful effects of fried potatoes on small children (2013, p. 23)."

• Putting the author's name in the parentheses as well:

  • "One study found that small children are enraptured by fried potatoes and would eat as many as allowed (Orlofsky, 2013, p. 23)."

Capitalize titles: If citing a title in-text, capitalize the key words (unlike the Reference list, in which only the first word of a title is capitalized).

For quotations longer than 40 words, the text must be block-indented and the parenthetical citation must come after the sentence's punctuation.

In 2008, Burhans noted that:

As more and more Florida potato farms are lost to development, recent events in potato breeding may reduce chippers’ dependence on early Florida potatoes. At the time of this writing, new varieties, such as Dakota Pearl and Glacier Chips, have been successfully stored into June, well past the April date when storage potatoes are usually giving out. According to some, these varieties will be able to tolerate storage temperature fluctuations as great as ten to twenty degrees without turning to sugar, chipping white the whole time. (p. 9)

REFERENCES

Article

Author(s). (year, month day). Title of article. Journal Title, volume(number), page number-page number. DOI or URL.

Example:

Orlofsky, V. L. (2013). French fries and small children. Journal of Fried Foods, 43(2), 19-34. https://doi.org/1234567/etc

Book

Author, A. A. (Year of publication). Title of work: Subtitle of work. Publisher Name.

Example:

Burhans, D. (2008). Crunch!: A history of the great American potato chip. University of Wisconsin Press.

Formatting requirements:

• The list is titled "References" (no quotation marks).
• Each work cited in your paper must be included, and the list is to be alphabetized by first author.
• Each entry in the Reference list should have a hanging indentation (every line after the first line indented 1/2 inch from the left margin).

IN-TEXT CITATIONS

You refer only to authors by their last name, either in the use of the author's name in the text itself or in the parentheses. Use a page number if what you're citing is directly from a page (a quote or observation), but do not if you're speaking more generally about the gist of the work. The last of multiple authors is marked with an ampersand in parentheses, but spell out "and" if used in text.

• One author

  • In text: Orlofsky (2013) studied the effects of...fried potatoes (p. 12).
  • Parentheses: (Orlofsky, 2013, p. 12)
     

• Two authors

  • In text: Orlofsky and Walsh (2014) noted...
  • Parentheses: (Orlofsky & Walsh, 2014)
     

• 3+ authors

  Use "et al." (Latin for "and others") to abbreviate multiple authors.
  • In text: Orlofsky et al. (2015) suggest...
  • Parentheses: (Orlofsky et al., 2015)
  • Note: if repeated use of the first author with et al. would be confusing (multiple works cited by the same first author), then write out all the names in text and then cite them parenthetically with more names before the et al.:
    • Orlofsky, Walsh and Espinel (2015) suggest.... (Orlofsky, Walsh & Espinel, 2015)
    • Orlofsky, Walsh, Espinel, Smith and Valverde (2016) discuss.... (Orlofsky, Walsh, Espinel, et al., 2016)
       

• Unknown author

  Use the title along with the year, in quotes if an article, in italics if a book:
  • French fries are a popular snack ("Potatoes Fried in Oil," 2019).
    • Note that while the article title would be in sentence case in the reference list (only first word capitalized), when cited in-text, it's written in title case (all words capitalized).
       

• Organization as author

  Write out organization in text and in the citation:
  The U.S. Food and Drug Administration (2017) suggests...
   

• Two or more works in the same parentheses

  Order them alphabetically, separate with a semi-colon:
  (Orlofsky, 2015; Walsh, 2018)

REFERENCES

Ebook

Per the Purdue OWL APA guide: "It is not necessary to note that you have used an eBook or audiobook when the content is the same as a physical book. However, you should distinguish between the eBook or audiobook and the print version if the content is different or abridged, or if you would like to cite the narrator of an audiobook."

For example:

Lastname, F. M. (Year). Title of book. Publisher. URL

Lastname, F. M. (Year). Title of book [ebook edition]. Publisher. URL
