The "Publication Manual of the American Psychological Association" contains style and format guidelines for academic works. It includes information for citing a wide variety of sources, both established works such as books and sources of information such as press releases.
If information from a press release is used, include an in-text citation. If a specific author is mentioned, use that name. Otherwise, the organization involved in the release is considered the author. After the information is presented, include the author's last name or the full name of the organization, a comma and the year of the press release inside the parentheses, such as: (The Movie Corporation, 2013).
When a citation is included with the text, it also must be listed on the references page at the end. First, list the author. If it is an individual, use the last name, a comma and initials followed by a period. If it's an organization, indicate the full name followed by a period. Write the year of the release within parentheses, followed by a period. Then, write the title of the release in sentence case, "[Press release]" followed by a period. Finally, write "Retrieved from" followed by the URL. For example, an entry could read: The Movie Group. (2013). What's happening this summer [Press release]. Retrieved from URL
