# How to add a footnote mark next to author name

I need to add a mark (e.g., a star) next to an author name and a footnote with this mark at the bottom. Something similar to \footnote but at the author name.

I use an ACM format article. I found some previous posts suggest using \thanks but this does not add a mark next to the author's name.

How to add a mark as a superscript to author's name and this mark also shown to the footnote?

Here is my script using \thanks which adds a footnote but not mark or number attached to it:

\documentclass[sigconf]{acmart}
\usepackage{array}
\usepackage{booktabs}
\usepackage{makecell, booktabs, caption}
\usepackage{footnote}

\begin{document}

\author{Author}
\thanks{First author.}
\affiliation{
\institution{Uni.}
\city{C}
\country{C}}
\email{xyz@mail.com}

\title{Title}
\maketitle

\begin{abstract}
Abstract
\end{abstract}

\section{Section1}
Section.
\end{document}


The document class you are using has a built in function for that, check out the manual at http://ftp.math.purdue.edu/mirrors/ctan.org/macros/latex/contrib/acmart/acmart.pdf

If you want the affiliation to appear under each author you use the \affiliation command, (in order: \author, \orcid, \affiliation \email).

If you want the affiliation to be in a footnote (with a footnote sign) you replace the affiliation command with \additionalaffiliation. If you do that make sure you put the email inside the affiliation block.

If you need just anote (like thanks) you can use \authornote.

A full MWE:

\documentclass[sigconf]{acmart}
\usepackage{array}
\usepackage{booktabs}
\usepackage{makecell, booktabs, caption}
\usepackage{footnote}

\begin{document}

\author{First Author}
\authornote{some other note}

\institution{Uni 1.}
\city{City1}
\country{Country1}
\email{xyz@mail.com}
}

\author{Second Author}

\institution{Uni 2.}
\city{City2}
\country{Country2}
\email{abc@mail.com}
}

\title{Title}
\maketitle

\begin{abstract}
Abstract ...
