Conduct the interview necessary to fulfill research on your journal article. Write down pertinent questions prior to the interview. Get as much information from the source during the interview as you can, because you may not have the opportunity once the interview is over.
Review the material that you gathered during the interview process. While you are outlining your article, place prospective quotes to be used in the outline. Correlate the information that you received into desired and appropriate topics where it will add to the presentation of your ideas and support any theories that you have.
Give credit to the interview source prior to using the first quote or idea from the source. When you are getting ready to interject the first quote retrieved from a source in an interview, introduce the source fully to your audience. Give the person credit for the information and tell your readers his credentials and professional affiliation prior to quoting him. For example: "Dr. Susan Smith, a professor of sociology at City College, states that ..." and continue with your quote from there.
Cite the source in parentheses using the format of Last Name, year of interview after subsequent quotes. Because you have already given the interview source full credit in the first quote, you do not need to do it again. Instead, simply attribute any further information gathered in this format. For example, after a second quote you would provide (Smith, 2011) to end the citation.
