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. – Jukka Suomela Jun 24 '11 at 18:32
Hmm, when I add \toappearbox{something} that does not change anything... What am I missing? – fgysin Dec 14 '11 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).

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

This solution works good. Thanks. – Nathan Farrington Jun 24 '11 at 17:37

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

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

Thank you! short & simple :) – mOna Jul 31 '15 at 8:00

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}
