# How to remove the copyright box on a paper that uses the ACM sig-alternate.cls class file?

The ACM provides a LaTeX template called sig-alternate.cls (webpage, class file). The current version is 2.4 released in April, 2009.

I would like to submit a paper for review using this class file. Unfortunately, the class file reserves some space at the bottom of the first page in the first column for a copyright notice. This copyright notice is required for the camera ready version of the paper, but not for the initial paper submission. How can I remove this copyright notice and reclaim this space?

• A non-answer, for the sake of completeness: The standard way to remove the copyright notice is to use the \toappearbox{...} command. This allows you to replace the copyright notice with a boxed text. This does not save any space, but usually this is a good feature: you can have identical layouts in the camera-ready version and in your own version. Jun 24, 2011 at 18:32
• Hmm, when I add \toappearbox{something} that does not change anything... What am I missing? Dec 14, 2011 at 10:17

Use the etoolbox package and its \patchcmd macro to selectively change sig-alternate' s definition of \maketitle, i.e. remove the \@copyrightspace macro (which is responsible for the copyright space).

\documentclass{sig-alternate}

\usepackage[english]{babel}
\usepackage{blindtext}

\usepackage{etoolbox}
\makeatletter
\makeatother

\begin{document}

\author{lockstep}
\title{How to remove the copyright space}
\maketitle

\blinddocument

\end{document}


(The blindtext package is only used to add some dummy text to the example.)

The accepted answer somehow doesn't work for me, but I found another solution here.

Simply add the following lines before \begin{document}:

\makeatletter
\makeatother

• Does not work for me. May 18, 2018 at 22:53
• worked for me under overleaf Oct 27, 2018 at 2:56

I fixed the problem by writing \setcopyright{none} before \begin{document} at the top. FYI I was using overleaf.

• I tried all the of the above and only this one worked. I am using Sharelatex.com. Dec 29, 2017 at 9:40
• didn't completely remove it on the ACM 2020 template Dec 11, 2019 at 14:41
• The command removed the copyright statement. Still the conference, ISBN, doi remains. By the way, I was using texmaker/texlive. Dec 4, 2020 at 1:08
• Same for me. This removes the copyright statement but the conference, ISBN, doi remains. Sep 1, 2021 at 7:01
• Look to @Jasper Uijlings's answer for removal of conference, ISBN, doi Dec 14, 2021 at 16:50

In the newest format (e.g. ACM MM 2020), you can set nonacm and authorversion in the documentclass:

\documentclass[sigconf,authorversion,nonacm]{acmart}


• That should be the accepted answer! :) Apr 22 at 15:00
• should be pushed higher

According to the documentation in the template source code:

• If you use the [preprint] option, the copyright text is removed but the space is preserved.

% ACM SIG template
\documentclass[preprint]{sig-alternate}

• If you use the [preprint] option of the template, you can use \toappear and \toappearbox to replace the copyright text. You must define the text to appear before issuing \maketitle. For instance

% ACM SIG template
\documentclass[preprint]{sig-alternate}
% text to appear
\toappear{To appear in the most incredible conference}
% other commands
\begin{document}
\maketitle
% other commands
\end{document}

• If you want to remove completely the copyright space, you can redefine a @copyrightspace variable used to create the box at the bottom. You must redefine it before the \maketitle

%% remove the box
\makeatletter
\makeatother

• If you want a smaller box, you can redefine the @copyrightspace variable too. Originally, the height of the box is 1". You can define a different size. For instance, the following code produce a smaller box. Note the \setlength with 0.2pc instead of 1pc

\makeatletter
\begin{center}
\setlength{\unitlength}{0.2pc}
\put(0,-0.95){\crnotice{\@toappear}}
\end{picture}
\end{center}
\end@float}
\makeatother


I prefer the answer here: How to remove conference information from the ACM 2017 SIGCONF template?.

\settopmatter{printacmref=false} % Removes citation information below abstract
\renewcommand\footnotetextcopyrightpermission[1]{} % removes footnote with conference information in first column


Use the preprint format will also remove the two-column layout, which I want to keep.

The following will replace the copyright text with blank or whatever you prefer. However, this will not reclaim the space, but you might need that for the camera ready version anyway.

Add the following before the \begin{document}

• For a text or blank with a rectangle around: \toappearbox{My-text-or-blank}
• For a text or blank with no rectangle: \toappear{My-text-or-blank}

For those who are looking to change the footer ACM text just put the following code before the document beginning and good luck.

\makeatletter
\def\runningfoot{\def\@runningfoot{}}
\def\firstfoot{\def\@firstfoot{}}
\makeatother


## Change ACM default Format:

You can use the following commands to remove copyright, reference format and footer/header of ACM default format:

\settopmatter{printacmref=false}
