I'm going to resubmit a 'major revisions'-paper to a journal. In the cover letter I describe changes I've made. Obviously, I mention some other papers in the debate:
"I developed and strengthened my criticism of XYZ(2010) in the following way..." etc.
Which reference-style should I use. (Reference section looks stupid at the end of a letter, doesn't it?) Or should I treat references in the manuscript itself as a reference section for the letter?
