Is it possible to add more than one corresponding author to an article?

No, because it is THE corresponding author. All the other co-authors have been let off doing secretarial work and are busy back at their research.

It is very common to include the E-mail address of all co-authors.

If there is no corresponding author tagged, then you are free to contact any of the authors (people will usually try the first-mentioned author first).

Yes you can. If it is correct or not that is another story. You can put more than one corresponding author in an article. I have one article with two corresponding authors and I saw other articles in the same situation. Just include in the file of manuscript when listing the authors the asterisk in both corresponding authors and them put below the information of both of them (Phone, email etc).

Obviously you are anticipating a flood of correspondence, so you have to asterisk more than one co-author to handle the flood of queries!

But if there are more than one corresponding author, with whom the journal will communicate during the process of publication. Sound strange.

You then create a situation of 1st corresponding author, 2nd...!

The question sounds a bit naive, but we are here on RG to support ANYONE. So humor is positive, but only with ONE corresponding author.

Hi, of course, shared corresponding authorship is accepted by some journals. See f.e. here:

Haschemi, A., P. Kosma, et al. (2012). "The sedoheptulose kinase CARKL directs macrophage polarization through control of glucose metabolism." Cell Metab 15(6): 813-826. (Shared corresponding authors: Haschemi A, Pospisilik AJ)

Yes, it is possible and the decision relay on the editor of the journal. There are not ethical issues. I did it a couple of times and will continue if necessary. It may happens the research to be published requires the blend of different technical field of expertise. Also, principal investigators can bring funding from different sources seeking the technical solutions. The most important, however, is that the corresponding authors may had brainstormed as a team sharing equal credits for the intellectual contribution. Readers can contact one or both authors depending on the area of interest. Not giving this possibility will reduce team-working. Bottom line, explain your reasons to the editor when submitting your share article. Cheers!

@Haslacher. Thanks for the info. But with whom the journal will communicate in that case.

Hi Subrata, it depends on a) whether the journal offers the feature of shared contributorships and b) how the submission process is designed.

In most journals, the person who submits the manuscript by an online managing system (and thus communicates with the journal) is not necessarily the one who is the declared corresponding author. That means, that - when you enter all the co-authors in the online-tool - you can assign persons to the function "corresponding author", irrespective of whether this person communicates with the journal or not. However, the term "corresponding author" is quite historical; it just means, that the author bears responsibility for all communication dealing with this paper since he or she is the most experienced and senior person among all co-authors.

The corresponding author, as for my personal knowledge regarding the Romanian situation, is in most cases, I would say, the person who has done the most work, or the one who "owns" the project. One also has to weigh in the intellectual work behind the project as a whole and from that perspective the person who has done the work, perhaps a detail in a much bigger perspective, may not be the appropriate person for details although that person has done most of the work for the paper in question. So in some cases the question is definitely harder to answer. Not being corresponding author, does not necessarily detract much from being first author.

Is it really necessary?

It is logical. I believe shared corresponding authorship can be accepted.

In my experience the corresponding author is not always the person that has done most of the work. In a lot of cases, the corresponding author is the person with time communicate with the editors and sort questions among co-authors. Having one or various corresponding authors may varied from discipline, editorial requirements, volume of correspondence expected, division of work (in some articles co-authors clearly define their roles as theoretical or methodological experts) or authors' preference. An interesting article regarding corresponding authors is Teixeira da Silva, J. A., Dobránszki, J., Thanh Van, P. & Payne, W. a. (2012) Corresponding authors: Rules, responsibilities and risks", The Asian and Australasian Journal of Plant Science and Biotechnology (http://www.globalsciencebooks.info/JournalsSup/images/2013/AAJPSB_7(SI1)/AAJPSB_7(SI1)16-20o.pdf)

until now I thought that it is not really necessary but based on responses here, there are few rare cases.

I did not think it was possible, it seems a good thing

Yes. I did on two papers. You can always ask for it, the worst thing that can happen is they say it's not possible.

You can have more than one corresponding author, however, one of them should act as the "Guarantor". Guarantor is the person who is usually have its role in Corresponding author, but in this case one of them should be the guarantor and he/she should be a man who supervised the whole research and the team worked under his/her supervision.

In my (limited) experience, the first author who is typically the submitting author is automatically designated as the corresponding author in the process of communicating with the journal in terms of submission, revisions, and production issues. But as some have pointed out above, the corresponding author listed on a published article has a different purpose, namely that if any reader wants to contact the group with questions, interviews, request additional resources alluded to in the publication, etc. they should write to the corresponding author. So, the corresponding author needs to be someone who is completely knowledgeable about the content of the article and can answer any questions that may arise.

The reason that we listed two corresponding authors on my recent articles is because while I was the first and submitting author, I do not necessarily anticipate being with my current institution long-term (this is not uncommon for graduate students, postdocs, and other early-career researchers), so I listed both myself and the PI as the corresponding authors so if I am not around when the reader wants to contact me they can contact the PI.

yes you can, 

look in to the this article, 

You can consider two people as CR, but not sure about more than 2 CR.

you can do  - better give email if of all authors  along with the address

sorry it is email ID

It is possible. There are even papers with more than two corresponding authors (3 and probably more)

no one will reply

you can have two , but the norm and practicality of having one CR author will facilitate quick responses to reviewers, editors, gallery proof reading. otherwise each one will depend on the other.  

fix responsibility on one

No, it cannot be done. However, you can add some emails in corresponding author's contact place.

Verily, adding more than one corresponding author to a particular article does not hold true. A manuscript should have one corresponding author but the email address can be more than one. So Omid you are right

Yes you can but it is not normal.

For sure there are many articles, even in top journals, which have two corresponding authors.

The Important question here would be, whether is it normal/ ethical practice or are there any specific rules/ guidelines written somewhere on this issue?

Would be nice to hear from seniors.

Most of the national and international journals guide lines corresponding author should be only one and he or she will be taking care of the article till the publication

Dear Chalamala,

I think that the answer is "NO"; otherwise, it depends on the journals. Maybe, you can contact the editor and s/he might permit that.

It sounds quite strange dear researcher . But then 1&2 corresponding authors may be maintained provided that journal have the provision. Any of them can do the task and then transmit the information of corrections to other co-authors as well before final submission of revision. In this kind of situation, the chief editor must be written to comply with the journal guidelines for authors.

Yes, you may, but is it necessary.

I think that there can only be one corresponding author per article

only one the one who make submission for the article,

and then you can make coauther

so only one

for coauther some journals ask for their contact but on the paper you put only the email of corresponding one

''Is it possible to add more than one corresponding author to an article?'' It is possible, but, in my opinion, it is not correct. Unless the percentage contribution for this specific activity is shown clearly in the article, regarding cases with more than one corresponding authors. It is a matter of ethics.

Regards 

My own opinion here is that the corresponding author should be one only. Why? Looking at the authors' guidelines of almost all the journals, you realize that they specifically mention corresponding author not "authors" hence it is only right to use a single corresponding author.

Yes, it can. As in my case, some of my papers we were more than one corresponding authors, for ex.

But some of the journals are restricted to one cross Author only.

Check the journal's author guidelines 

It simply depends on what the journal requires

The concept of corresponding author is not only for communicating purpose. One or more authors who have conveyed the basic idea, formulated and planned the research work can be corresponding author. In today's, multidisciplinary work, multiple brains could initiate an idea, and formulate an article. Even students can also be the corresponding author, if the entire concept belongs to them..

The concept of corresponding author is misinterpreted of only being for communicating purpose. 

It is not very common, but there are some papers that uses it.

Best Regards

SAM

Thank you Serguei. I will take in consider your advice.

Yes, I did! Why not?

Yes you can. You can put more than one corresponding author in an article, but you must include the details for each author for ex. (phone, email, etc).

Agree.

Yes, you can. An article can have more than one corresponding author. Elsevier allowed me to do this in my previous accepted manuscript.

yes, it is possible. although, the manuscript has to be uploaded from the email account of any one. Two or more corresponding persons should be designated within manuscript

It is possible to submit a paper with two corresponding authors. For more information you could check the following link:

" While some journals allow the practice of including two contact authors or corresponding authors, many journals do not. In your case, having two corresponding authors is a requirement for your paper. If you submit the manuscript with one corresponding author and explain in the paper or cover letter that you need to have two, you cannot really be sure whether the journal will allow this. If the journal does not allow, you will have to either go ahead with one corresponding author or withdraw your paper. The withdrawal process might be time-consuming and an additional hassle for you.To avoid this, you can send a pre-submission inquiry to the editor rather than submitting your manuscript. In the email, you can explain why you need two corresponding authors and two first authors, inquire if that is acceptable, and if so, how to submit your paper on the online system. If the editor gives a positive reply, you can go ahead and submit your paper. In case the editor replies that the journal policies do not allow this, you can submit your paper elsewhere directly without having to wait for the withdrawal process to complete. "

recently I could do it, so yes, it's possible in some journals!

It depends on the journal, usually one paper, only

one corresponding author

I think so

Yes of course.

Absolutely possible.

yes, for some journals.

Yes it is possible but completely depends upon the journal.

yes you can, but depends to the journals

It is possible to have two corresponding authors.

Yes

Only mention the information of co-corresponding authors (e.g., email address) is not enough. If your system check the it in the e.g., web if science. You can see there is still only one corresponding author.

So, it depends on the rule of journal.

It depends on the publisher.

Yes possible, we can use two corresponding if publisher or journal allows.

Yes, mostly two is acceptable and also depend on the journal.

Thanks for all the answers!

it is possible to have two corresponding authors, but it also depends on the journal itself.

Yes, it's possible to add more than one corresponding author to your article but it largely depends on the journal/publisher policy. Mark them with an asterisk and provide their contact information in the manuscript. If the journal/publisher has a problem with that you will be contacted.

It depends on the publisher. Some Journals allow us to select two corresponding author.

Very usefull information indeed!

It is possible if the journal agree to that. Some journals may prefer to have two corresponding authors for easy accessibility.

that's a very good information, good to know

Yes it is possible, because in some cases the first author cannot deal with the submission processes due to variety of reasons such as the publication raises after the study of PhD student, but the student may be out of science, or the first author does not want to spend time for submission processes. Anyhow, nothing is wrong to have two or more corresponding authorship.

I think it also depends upon the journal

Yes, it can be possible to include two corresponding authors. It depends on the journal also.

How about two first authors ? Is that possible to have two first authors ?

yes you can, specially if each one of them participate in part of the article it is required to have both as correspondence.

Does anyone know a journal that specializes in medical physics and accepts two corresponding authors?

I consider it appropriate when collaboration on the article has been equitable.

Yes, it can be.

Dear Ahmed Samy El-agwany

Some journals allow that and in some others, this is not allowed. It depends. but, some reviewers and associate editors may reject the paper because of this.

Yes, it is possible to add more than one corresponding author in an article. But it depends on the publishers.

thank you. Unfortunatly not all journals allow to do this!!!!

While some journals allow the practice of including two corresponding authors, many journals do not. However, most journals do not mention anything about the permissible number of corresponding authors in the author guidelines. This can be a problem for authors who wish to have more than one corresponding author for their paper. In this case, the authors lost a lot of time in formatting the paper according to the journal guidelines and preparing for submission, only to be rejected because of the issue of two corresponding authors. It is always preferable to send in a pre-submission inquiry to a journal to find out whether the journal allows this.

With research becoming increasingly collaborative, having more than one corresponding author for an article is not unusual. There are many reasons why two corresponding authors may be required. For instance, two different laboratories may collaborate on different aspects of a paper, and one corresponding author would be required from each lab to be able to answer readers’ questions on the two aspects. Another situation that commonly requires two corresponding authors is when the first author (who is also the corresponding author) is a PHD student or a postdoc who does not intend to remain in the same lab or even in academia for a long time. In such cases, the PI of the lab is usually the co-corresponding author who is available to answer readers’ questions or address requests for additional resources when the first author is unavailable.

Of course, you can. It is even possible to have a corresponding author and two/more co-corresponding author. It really depends on the contribution of the team worked on a project.

It is meaningless to have more than one corresponding authors in a paper. Corresponding author means who communicate paper to journal.

of course, it is possible. But some journals will not allow you to introduce more than one author, so you have to talk to the editor if you would like to do that.
