What should I do if I have published a paper that I did not write? To start with, let me confess a sin that I have committed a few years ago. A friend of mine asked me to proofread several of his papers before sending them for publication. After helping him several times without expecting anything in return, he offers to included me as one of the authors of another paper after I proofread it. Being immature and greedy, I have accepted the offer, which is a great mistake. Later the paper was published and I was listed as one of the authors of the paper, and I understand nothing about the paper itself. Now I am facing the mistake that I have made and have decided to do something about it.


Should I always exclude the paper from my resume? Although I was officially listed as one of the authors, I do not feel that I contributed to any part of the paper except proofreading.
Is there anything else that I should do about this situation?
Be sure to never do this again. 

I think it's reasonable to remove the paper from your CV and forget about it. Otherwise, people are definitely  going to ask you about it in interviews.

Other than that I don't think there's much you can do to remedy this.
