Begin your citation with the first initial and last name of the person you interviewed. Place a period after the person's first initial, and a comma after the person's last name. For example:
J. Smith,
Add the phrase "personal communication" followed by a comma. For example:
J. Smith, personal communication,
Conclude your citation with the month, day and year on which you conducted the interview. Place a comma after the day. For example:
J. Smith, personal communication, July 7, 2010
Enclose your citation in parentheses. Position it within the text so that it comes directly after the quote or paraphrase. For example:
One interviewee found it "hard to believe" (J. Smith, personal communication, July 7, 2010) that anyone would want to eat such bland food.
