\endnote inside \author tag

Question

I have a rather complicated document of the {scrartcl} class, derived from the .tex file I downloaded off this page http://www.howtotex.com/templates/template-added-two-column-color-article/

I try to use the endnotes package to specify the authors' affiliations (it won't fit in the template prescribed format). Sadly I cannot use the \endnote{} macros inside the \author{} field. Compilation fails on that line with:

./openpr.tex:81: Argument of \reserved@a has an extra }.

I have tried the enotez package but the line where I put the endnote fails with:

./openpr.tex:81: Use of \enotez_endnote_aux:w doesn't match its definition.

I get the error with this minimal example:

\documentclass[DIV=calc,paper=a4,fontsize=11pt,twocolumn,hyperref]{scrartcl}                        % KOMA-article class
\usepackage[english]{babel}                                     % English language/hyphenation
\usepackage{endnotes}                                           % Used for annoting author affiliations at the ened

\usepackage{titling}                                                            % For custom titles

\title{Concepts}                    % Title of article goes here

\author{Lala \endnote{a}}                                   % Authors' names goes here
\begin{document}
\maketitle
\theendnotes
\end{document}

Apparently it works if I remove \usepackage{titling}, but I need that to make my title sexy :(

Could you guys help me get an endnotes' section with all my author affiliations?

Answer 1

Edit in reaction to comments for using the same endnotemark more than once:

With endnotes:

Use \endnotemark[number] and \endnotetext[number]:

\documentclass{scrartcl}
\usepackage{endnotes}

\title{Concepts}
\author{Lala\endnotemark[1], Lilo\endnotemark[2],
        Lolita\endnotemark[1], Lulu\endnotemark[3]}

\begin{document}
\maketitle
\endnotetext[1]{Institute ABC}
\endnotetext[2]{Institute A\&O}
\endnotetext[3]{Institute XYZ}
\theendnotes
\end{document}

With enotez:

Starting from version 0.6 you can use the following approach. The package is now able to use a label-ref mechanism, so you do not have to keep track of the number.

^{For older versions see answer’s revision history.}

\documentclass{scrartcl}
\usepackage{enotez}
  \makeatletter % taken from documentation
  \def\endnotemark{\@ifnextchar[{\@endnotemark}{\@endnotemark[\theendnote]}}
  \def\@endnotemark[#1]{\enotezwritemark{\enmarkstyle#1}}
  \makeatother

\title{Concepts}
\author{Lala\endnote{Institute ABC}\label{lala}, Lilo\endnote{Institute A\&O},
        Lolita\endnotemark[\ref{lala}], Lulu\endnote{Institute XYZ}}

\begin{document}
\maketitle
\printendnotes
\end{document}

Original answer:

With endnotes:

Using \endnote with \protect works fine.

\documentclass{scrartcl}
\usepackage{endnotes}

\title{Concepts}
\author{Lala\protect\endnote{abc}}
\begin{document}
\maketitle
\theendnotes
\end{document}

With enotez:

You have to use \protect again:

\documentclass{scrartcl}
\usepackage{enotez}

\title{Concepts}
\author{Lala\protect\endnote{endnote}}
\begin{document}
\maketitle
\printendnotes
\end{document}

For \protect see also What is the difference between Fragile and Robust commands? and Alain Matthes’ answer to What is the purpose of \protect?

Answer 2

Even though it is not exactly what you needed, I tried Using scrartcl class built-in macro options \thanks{}[Page 57 Ch:3] for footnotes and \and{}[Page 58, Ch:3] for including multiple authors.

There are many header, footnote, title options mentioned for this class , there is no need to use additional packages to tailor it. KOMA-article classes are most flexible enough.

To achieve endnotes effect \appendix or \newenvironment can be defined.

  \documentclass[DIV=calc,paper=a4,fontsize=11pt,twocolumn
  ,hyperref]{scrartcl}  % KOMA-article class
  \usepackage[english]{babel}  % Englishlanguage/hyphenation
 %\usepackage{endnotes}  % Used forannoting author affiliations at the end
   \usepackage{titling}    % For custom titles                                                         
   \title{Concepts} % Title of article goes here
   \author{{Lala,Dept,University} \thanks{Lala Team},\and{ Others,Research     
  Center} \thanks{Others Members},\and{ Also, Teacher, School} \thanks{Also 
  People}} % Authors' names goes here 
  \begin{document}
  \maketitle
  \end{document}
