# Adding Multiple Authors with Different Affiliation in LaTeX Article

Updated:

I want would like to add more than one author affiliation in latex article. To make this I have tried with the following latex code :

\documentclass{article}
\usepackage{authblk}
\author[1]{A. Author}
\author[2]{B. Author}
\author[3]{C.  Author}
%\author[2]{Corresponding Author\thanks{email@2nduniversity.com}}
\affil[1,2]{Institution of the Authors from  University}
\affil[3]{Institution of the Authors from  College}
\affil[1]{Email id: aa@gmail.com}
\affil[2]{Email id: ba@gmail.com}
\affil[1,3]{Email id: ca@gmail.com}
\title{Title of the Presentation}
\date{}
%
\begin{document}
\maketitle
Main Part of document here.
\end{document}.


But it does not give my desired output. I want exactly like this :
How can I do this?

• You have some mistakes like : 1)not A in first authors name, 2) third author has number one instead of [3]... The only difference in the result after these changes is a blank line after author that can be solved with the "fix" \author[3]{C. Author\vspace*{-10pt}} and that the emails are in separate lines. Do you want the emails in the same line too? Dec 16 '17 at 8:44
• @koleygr thank you for point out my mistake.

Apart from correcting the typo in \author[1]{C. Author}, which should be \author[3]{C. Author} as pointed out in the comments, you can use the approach in this answer to make the emails appear on the same line. The following code block determines what appears between affiliations (in this case, a comma followed by a space):

\makeatletter
\renewcommand\AB@affilsepx{, \protect\Affilfont}
\makeatother


To make this change local, you should enclose all the email code in curly braces {}. To include the Email ids: header, you can use an affiliation whose tag is a space (\affil[ ]{Email ids}) and : as separator:

{
\makeatletter
\renewcommand\AB@affilsepx{: \protect\Affilfont}
\makeatother

\affil[ ]{Email ids}

\makeatletter
\renewcommand\AB@affilsepx{, \protect\Affilfont}
\makeatother

\affil[1]{aa@gmail.com}
\affil[2]{ba@gmail.com}
\affil[1,3]{ca@gmail.com}
}


The full code is as follows:

\documentclass{article}
\usepackage{authblk}
\author[1]{A. Author}
\author[2]{B. Author}
\author[3]{C.  Author}
%\author[2]{Corresponding Author\thanks{email@2nduniversity.com}}
\affil[1,2]{Institution of the Authors from  University}
\affil[3]{Institution of the Authors from  College}
{
\makeatletter
\renewcommand\AB@affilsepx{: \protect\Affilfont}
\makeatother

\affil[ ]{Email ids}

\makeatletter
\renewcommand\AB@affilsepx{, \protect\Affilfont}
\makeatother

\affil[1]{aa@gmail.com}
\affil[2]{ba@gmail.com}
\affil[1,3]{ca@gmail.com}
}

\title{Title of the Presentation}
\date{}
%
\begin{document}
\maketitle
Main Part of document here.
\end{document}.
