We had a paper accepted in one of the top biology journals (IF=15). It is a work in which I participated in the part of computational biology, and was submitted by a colleague, she being the corresponding author since she is an expert on the field. We had a major revision and I had to do an outstanding work and a lot of calculations in order to have the paper accepted. I even developed a new approach. So now that we are at the proof stage, I would like to request her to appear in the paper as co-corresponding author since this is very important in my country. I do not know exactly how to do it. I will tell her to add me as co-corresponding with the text “to which all computational biology based correspondence should be addressed” since she is wet lab biologist. But I do not think this will be enough argument for her, i guess she will say initial ideas came from her side. What do you suggest for my “cover letter” to her?

    Is this even allowed by the journal? My experience has been that journals only allow one corresponding author. Feb 24, 2019 at 23:09

    Many journals I know allow several corresponding authors. And in addition, I have the experience that journals such as Scientific Reports allow adding co-corresponding authors during proofs stage Feb 24, 2019 at 23:10
  • Is there also prestige to being the single corresponding author in your or your colleague's countries? Because if there isn't you might well be overthinking this.

    Why don't you just say that being the correspondent author is valuable in your country? This shouldn't be a problem unless being the correspondent author is also valuable in her country. Feb 25, 2019 at 9:18

While I don't really understand the value of this to you, not being in your immediate culture, the solution is clear as it is in most similar situations.

If you want something, just ask for it. Give her your reasons why it is important to you and why you need this at this time. If you ask it as a favor and not as a demand you might be more likely to prevail.

You may not be successful, but nothing you do can guarantee success. Asking keeps it collegial and preserves your relationship for the future.

Yes, you contributed, but so did she, I assume. In most places corresponding author is just a task, not an honor.

I'll suggest that whatever happens in the handling of a single publication it is unlikely to have much of an effect on your career. Working for long-term relationships is, to me, much more important than any check mark on a box or minor point on a CV.

    Yes I agree completely on asking it as a favor instead of a demand. And also in the value of long term relationships. Thanks for the point Feb 25, 2019 at 21:18

What you write to your colleague is very similar to what you're writing here. You've strongly contributed to the computational side of this paper, and those computations form a substantial part of the paper. You feel that sharing corresponding authorship would accurately reflect both of your contributions. That's basically it.

You could also ask for a shared last authorship, and you should definitely consider asking for a shared first for your student who's done the computations.

Congratulations on the paper!

  • From my point of view, a shared last authorship is the same as sharing corresponding authorship. Otherwise, why do you think it is different? Thanks for the answer Feb 25, 2019 at 21:19
  • It feels the same to me as well. However, I think I've seen shared last authorships that were not all corresponding (and I've also seen corresponding authorships for people who weren't last authors) - but my memory could be playing tricks on me. Feb 26, 2019 at 8:05
