Parenthetical Versus Narrative In-Text Citations
Both the author and the date, separated by a comma, appear in parentheses for a parenthetical citation. A parenthetical citation can appear within or at the end of a sentence.
Falsely balanced news coverage can distort the public’s perception of expert consensus on an issue (Koehler, 2016).
If other text appears with the parenthetical citation, use commas around the year.
(see Koehler, 2016, for more detail)
When text and a citation appear together in parentheses, use a semicolon to separate the citation from the text; do not use parentheses within parentheses.
(e.g., falsely balanced news coverage; Koehler, 2016)
The author’s surname appears in running text, and the date appears in parentheses immediately after the author’s name for a narrative citation. The author’s name can be included in the sentence in any place it makes sense.
Koehler (2016) noted the dangers of falsely balanced news coverage.
In rare cases, the author and date might both appear in the narrative. In this case, do not use parentheses.
In 2016, Koehler noted the dangers of falsely balanced news coverage.
