# 1-column abstract in 2-column document

One often requires that the abstract of a paper should appear across the entire page, even in a two-column paper. The required trick is: ```latex \documentclass[twocolumn]{article} … \begin{document} … % \author, etc \twocolumn[

\begin{@twocolumnfalse}
  \maketitle
  \begin{abstract}
    ...
  \end{abstract}
\end{@twocolumnfalse}
]

``` Unfortunately, with the above `\thanks` won't work in the `\author` list. If you need such specially-numbered footnotes, you can make them like this: ```latex \title{Demonstration} \author{Me, You\thanks{}} \twocolumn[

... as above ...

] {

\renewcommand{\thefootnote}%
  {\fnsymbol{footnote}}
\footnotetext[1]{Thanks for nothing}

} ``` and so on.

As an alternative, among other facilities the [`abstract`](https://ctan.org/pkg/abstract) package provides a `\saythanks` command and a `onecolabstract` environment which remove the need to fiddle with the `\thanks` and footnoting. They can be used like this: ```latex \twocolumn[

\maketitle             % full width title
\begin{onecolabstract} % ditto abstract
  ... text
\end{onecolabstract}

] \saythanks % typeset any \thanks ``` The [`memoir`](https://ctan.org/pkg/memoir) class offers all the facilities of [`abstract`](https://ctan.org/pkg/abstract).
