Multiple authors with different primary affiliation, but same additional affiliation

I am writing a paper with 2 authors that have different primary affiliations. However, they both have a common additional affiliation. Currently, this is what I do:

%\author{Author Two\footnotemark[1]} % Next attempt: use this line instead of \author{Author Two} and \additionalaffiliation

\begin{abstract}
Here is my abstract
\end{abstract}

\keywords{this, that, another}

\maketitle

\end{document}


Unfortunately, this creates two separate footnotes that say the exact same thing: "Also with Secondary Organization." Is there any way to just use one symbol next to both names so that they reference the same footnote?

I've also tried:

\author{Author Two\footnotemark[1]}


for the second author's name instead of using \additionalaffiliation again. This does produce the desired effect, but with a side effect too. Elsewhere in the document, when the authors are referenced, it outputs:

Author One, Author Two[1].

• Welcome to TeX.se. Instead of posting code fragments, please put your fragments into a complete compilable document that shows the problem. In particular, what document class or package defines the macros that you are using? – Alan Munn Jul 20 '17 at 19:13
• I am using \documentclass[sigconf]{acmart}. I didn't post the actual full document since it would be rather large and include work in progress that isn't ready to be made public yet. – Tommy Marrinan Jul 20 '17 at 19:58
• So edit your question to make the document compilable. You don't need to post the whole document, for this problem it doesn't even need to contain any main text. Put the fragments in the \documentclass{acmart} ...  and add only the author code plus whatever else is necessary to make it compilable. See minimal working example (MWE). – Alan Munn Jul 20 '17 at 19:59
• Ok - should be a compilable document now – Tommy Marrinan Jul 20 '17 at 20:17
• May be you can fill a bug report. Altough there are some closed bugs reports related to multiple affiliations and more compact headers, your question looks valid and different than them. – Jaime Apr 8 at 21:58

Here's a solution. I've made a new command \addauthornote which takes a single argument, a number corresponding to the n-th additional affiliation. This will add the footnote mark corresponding to that additional affiliation and add it to the current author.

Here's a complete example using 4 authors with 2 additional affiliations.

• The only problem with your solution is the metadata generated by the template. The ACM template use the commands \additionalaffiliation{} and \affiliation{} to create author metadata that automated-tools can extract. If you use your commands, or the official\authornote and \authornotemark, the corresponding metadata will be not generated. – Jaime Apr 8 at 22:10
