[Tex/LaTex] Switching between single- and multi-column format

formattingtwo-column

I'm trying to create a pdf for a journal where the authors are in multiple column format but the rest of the document/text is not. How can I get this to work? It auto formats the rest of my document into two columns. I'm exporting it to pdf and I'm using TeXworks.

\documentclass[10pt,twocolumn]{article}

\title{Article Title}
\author{
    First Author\\
    Department\\
    school\\
    email@edu
  \and
    Second Author\\
    Department\\
    school\\
    email@edu
    \and
    Third Author\\
    Department\\
    school\\
    email@edu
    \and
    Fourth Author\\
    Department\\
    school\\
    email@edu
}
\date{\today}

\begin{document}

\maketitle

\begin{abstract}
This part should be in a single column.
\end{abstract}

\section{Introduction}
\ldots 

\end{document}

Best Answer

The authors of an article document are always set in multiple columns, regardless of the twocolumn option. Removing twocolumn from your document options will yield this result:

\documentclass[10pt]{article}
\usepackage{lipsum}

\title{Article Title}
\author{
    First Author\\
    Department\\
    school\\
    email@edu
  \and
    Second Author\\
    Department\\
    school\\
    email@edu
    \and
    Third Author\\
    Department\\
    school\\
    email@edu
    \and
    Fourth Author\\
    Department\\
    school\\
    email@edu\\
\and
    Fifth Author\\
    Department\\
    school\\
    email@edu
  \and
    Sixth Author\\
    Department\\
    school\\
    email@edu
    \and
    Seventh Author\\
    Department\\
    school\\
    email@edu
    \and
    Eighth Author\\
    Department\\
    school\\
    email@edu
}
\date{\today}


\begin{document}

\begin{abstract}

\end{abstract}

\section{Introduction}
