In my paper, I am quoting someone, but it's not from any "source," really, it's merely from a conversation (erm... interview, kind of) that I had with him. He knew that he was being asked questions and would be used in my paper, it's not some random thing and I decided to use a quote. I, of course, introduced him the first time I used his name (i.e., John Smith, director of ABC Libraries, explained to me that blah blah blah.).
Do I need to cite him in a works cited page?
