I have a question about using zotero when citing interviews (that I have conducted). Under "Title" I put the interviewee's name, the organization they work for, the location of the interview, and the phrase 'interview by author'. In citations, this all comes out with quotation marks around it -- which I don't want. It looks like this: "Joe Smith, Greenpeace, New York, interview by author," June 11, 2012. (I am suppressing the "Author" field, because otherwise, it ends up like this: Joe Smith, "Joe Smith, Greenpeace, New York, interview by author," June 11, 2012.) How can I get rid of these quotation marks?

I tried entering 'Greenpeace, New York, interview by author' into the "Medium" field (instead of the Title field) and NOT suppressing the author, but then the "interview with" name (i.e. the interviewee's name) is not followed by a comma (which it should be, to separate the name from the information about the person - Greenpeace, etc. - found in the "medium" field). I then tried adding a comma to the "last name" field - which works in the footnote - but is likely going to be wrong in the bibliography.

Is there a way to get rid of the quotation marks that surround the title? Using "edit citation" doesn't let you modify the title, as far as I can see. Other ideas?
