I was recently informed that a manuscript that I submitted to a journal a long time ago has been accepted.
I submitted it as the sole author, however, my advisor had some comments and suggestions that I applied to the manuscript.
As a courtesy I would now like to add him as an author.
My question: can a second author, i.e. my advisor, be added once I receive the galley proof, or whatever that is called, to the manuscript.
Any thoughts would be highly appreciated.
Possibly related to this question.
