List the last name of the author and the year of publication in parentheses, if you are referencing a press release as a whole. For example:
(Smith, 1990)
List the author's last name, the year of publication and the page number in parentheses, if you are referencing a specific part of a press release. For example:
(Smith, 1990, p. 2)
Position your citation at the end of a direct quote or paraphrase of the press release. For example:
One press release stated that the company had "never taken part in any form of insider trading" (Smith, 1990, p. 2), although evidence to the contrary continued to mount.
Omit the author's name from your parenthetical citation, if you have already mentioned the author by name in the text. In this case, cite the year of publication directly after the author's name, and cite the page number directly after the quote or paraphrased passage. For example:
Smith (1990) stated that the company had "never taken part in any form of insider trading" (p. 2), although evidence to the contrary continued to mount.
