# \endnote inside \author tag

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?

Welcome to TeX.sx!. Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  texenthusiast Mar 26 '13 at 3:19
@texenthusiast Ok, I updated it. –  TheChymera Mar 26 '13 at 3:38
Once again: It works for me without and with titling! Otherwise you must provide a proper MWE. –  Speravir Mar 26 '13 at 15:27

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}


## 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?

The enotez code you just gave me returns ./openpr.tex:8: Undefined control sequence. for the line with either \theendnotes or \printendnotes on it –  TheChymera Mar 26 '13 at 4:26
No error here. Try a second compilation, it may be a remnant of the last run. –  Speravir Mar 26 '13 at 4:29
Nope - apparently it will not run unless I add a number in brackets after \endnote - this is a minor inconvenience, but for now it's ok. Sadly, in my document the \maketitle command stopped working after I implemented this. I am still trying to find out why, as the minimal example works. –  TheChymera Mar 26 '13 at 4:36
General remark: Read carefully, what the real meaning of “minimal working examples” is. Apparently you removed too much and did not show us, that you intend to use custom numbers. For the second: In first revision I used \endnotemark and \endtnotetext, see tex.stackexchange.com/revisions/104314/2. (But on the other side you left packages and options in, which are not needed …) –  Speravir Mar 26 '13 at 4:41
I fixed the \maketitle issue. But I still cannot use \endnote without specifying the number in brackets. Depending on whether or not I import the titling package in the header your code eitherfails at \printendnotes (if no titling) or at \maketitle (if titling). Also, I do not intend to use custom numbers - what gave you that Idea? I would rather just not be mentioning them the entire time. –  TheChymera Mar 26 '13 at 4:44

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}

This is sadly not what I am looking for, as I do not want this info cluttering my first page (or pushing up the text section on any other page) I would like to have the affiliations listed at the document end similarly to the bibliography. –  TheChymera Mar 26 '13 at 4:35
@TheChymera sorry may be i misunderstood, i will try if i can place them at end of document. –  texenthusiast Mar 26 '13 at 4:38
@TheChymera I could not using in-built class options, i feel sleepy. May be i will wait for other's suggestion, for time being use endnotes package, it works fine. –  texenthusiast Mar 26 '13 at 6:03
