With the GSA Style, quotations and borrowed phrases are indicated as such within the text, with the author's name and page number cited in parentheses. This variation is used instead of footnotes or endnotes.
When quoting or paraphrasing an author, begin the sentence by including the author's name followed by the date of publication in parentheses. At the end of the quote or paraphrase, include the page number(s) in parentheses. See example below.
According to Smith (2008), "warmer ocean temperatures can lead to the development of stronger hurricanes" (p. 133).
If the name of the author is not included within the sentence, include the author's name and the publication year at the end of the sentence with the relevant page number(s). For example:
"Warmer ocean temperatures can lead to the development of stronger hurricanes" (Smith, 2008, p. 133).
To cite a publication with two authors, include both authors' last names either within the sentence or in parentheses at the end of the sentence.
For publications with 3-5 authors, include the last name of each author the first time the publications is cited. For subsequent citations include only the last name of the first author and the phrase et al.
For publications with 6 or more authors, list the name of the first author followed by the phrase et al. for all citations.
