“Authors Response” or “Authors’ Response”? Recently, I received a decission letter from an IEEE journal. When I prepared my response, I became confused. The demand from editor is as follows:   


  Please start your paper file with an authors response to the review of [paper ID number] which  contains how you responded to the reviewers comments.  


My confusions are:


Which of the following titles should I use for my response?


  An Authors Response to the Review of Paper XXX
  Authors Response to the Review of Paper XXX


Should I drop an or not?
Which of the following should I use?


  Authors Response to the Review of Paper XXX
  Authors' Response to the Review of Paper XXX


Should I add an apostrophe at the end of authors?
I really doesn't matter: all of these are close enough to one another to be clearly sensible and have plausible arguments for why they might be reasonable. More importantly, none of them will make it into the published paper: they are merely a transient piece of communication between you and the editor and reviewers which will later be deleted.  As such, any of them is reasonable enough.

That said, personally, I would just say "Response to Reviews" and avoid the whole question.
