# Many corresponding authors in elsarticle class

I need to put 3 corresponding authors using the elsarticle class. The problem I found is that there is not '***' as superscript of the third author name.

\author{name1\corref{firstcorr}\fnref{firstfoot}}

\author{name2\corref{secondcorr}\fnref{secondfoot}}

\author{name3\corref{thirdcorr}\fnref{thirdfoot}}

\fntext[firstfoot]{Affiliation1}
\fntext[secondfoot]{Affiliation2}
\fntext[thirdfoot]{Affiliation3}


Example in which *** do not appear in the third author:

The email is shown without asterisks

How to fix it?

Thank you

• In my understanding, there should only ever be at most one corresponding author. Please clarify what you're trying to achieve by listing three corresponding authors. Your code doesn't make effective use of the \corref/\cortext machinery. If you simply mean to use it to state mailing addresses, you shouln't be using \corref/\cortext in the first place. – Mico Aug 26 '18 at 16:32
• @Mico , as many institutions give some additional points for being corresponding author, it is not extraneous to have more than one correspondig author – user1420303 Aug 29 '18 at 13:04
• In that case, you should contact the powers-that-be at Elsevier and communicate to them a feature request, viz., the ability to designate as many of the authors as "corresponding authors" as one wishes while using the elsarticle LaTeX document class. That's a feature request, and feature requests are off-topic for this site. – Mico Aug 29 '18 at 13:31
• And if the institution you're working for is sufficiently simple-minded and gullible to take the presence of the string "Corresponding Author" on the title page of a journal article as evidence that the author is indeed a "corresponding author", there's nothing to stop your (or anyone else...) from including the string "Corresponding Author" in the argument of \fntext, is there? – Mico Aug 29 '18 at 13:34
• @Mico , thank you for reply. Elsevier class documentation does not specify that limitation. Up to 2 correspondig authors works fine. Nevertheless, I do not ask for a feature request of the official Elsevier class. I ask for a TeX/LaTeX code that solve an specific LaTeX issue which can be summarized as how to get the asterisks in the right positions. I did so, but asterisk does not appear rightly. – user1420303 Aug 29 '18 at 13:41

(edited to discuss the use of \fntext directives to provide additional information about an author, such as that he/she is to be taken to be a "corresponding author")

You wrote,

If all you need to do is list the authors' correspondence addresses, you should definitely not be using the \corref/\cortext machinery to provide address-related information. Instead, use \address directives to state the authors' correspondence addresses.

A general comment: It usually makes little sense to list more than 1 author as "corresponding" author. The whole point of designating an author as the "corresponding author" is to channel inquiries, comments, suggestions, criticisms, and all other communications to a single person. If all authors of a journal article are in a position to react to communications about their journal article, there's simply no need to provide footnotes to point out that all authors are, in fact, qualified to receive communications related to the article.

The elsarticle document class actually allows one to specify 1 or 2 authors to be "corresponding" authors via \corref and \cortext directives. If, for whatever reason, you need to designate more than 2 authors as "corresponding" authors, I would recommend that you use \fnref and \fntext machinery to do so (and, conversely, not use the \corref/\cortext machinery).

Given the information you provided in your code fragment, it's probably a very good idea to employ \address directives to state the authors' correspondence addresses. If you need to provide email addresses as well, provide \ead directives immediately after the corresponding \author{...} directives.

In the following screenshot, I've highlighted the various footnote-type markers. Note that only 1 author is designated as the "corresponding" author.

\documentclass{elsarticle}
\title{A title}

\author[1]{Name1\fnref{firstfoot}}
\author[2]{Name2\corref{aaa}\fnref{secondfoot}}
\author[3]{Name3\fnref{thirdfoot}}

\cortext[aaa]{Corresponding Author}
