Notes: 

Include the name of the company or organization issuing the press release after the title of the press release (see pg. 39, "Reports and Handbooks: Basic Online Format," 1). Consider including an access date for online materials (see p. 39, "Reports and Handbooks: Examples," 2); when the access date is used in place of the date of publication, place it immediately after the country of publication (see p. 39, "Books, Monographs: Examples," 4). For URLs, provide the direct link to the press release whenever possible, not the link to the library database as per APA style (see pg. 38, "On-Line Sources"). If your only option is to provide the link to the database, provide the name of the database in place of the URL (see p. 40, "U.S. Government Documents: Example," 1).
