I'm looking for a solution that will allow me to prevent some parts of the final pdf file (header, footer) from being selected and copied. It is to allow easier quoting of longer parts of texts from documents that will be published.

Based on this answer, you could use accsupp to define a \squelch command:

\documentclass{article}
\usepackage{accsupp}
\DeclareRobustCommand\squelch[1]{%
    \BeginAccSupp{method=plain,ActualText={}}#1\EndAccSupp{}}

\begin{document}
This text is selectable \squelch{but this text isn't}.
\end{document}

The squelched text cannot be highlighted in Acrobat, and copying the whole line gives this:

This text is selectable .

It's easy to combine this with fancyhdr:

\usepackage{fancyhdr}
\fancypagestyle{plain}{%
    \fancyhf{}%
    \fancyfoot[C]{\squelch{\thepage}}%
    \renewcommand{\headrulewidth}{0pt}%
    \renewcommand{\footrulewidth}{0pt}%
}
\pagestyle{plain}

You could also define a variant \squelchstyle for use with KOMA-Script's \addtokomafont:

\def\squelchstyle{%
    \BeginAccSupp{method=plain,ActualText={}}%
    \aftergroup\aftersquelchstyle}
\def\aftersquelchstyle{\EndAccSupp{}}
\addtokomafont{pagenumber}{\squelchstyle}

This works even when viewing the document in evince. Amazing! –  krlmlr Mar 27 '12 at 11:38

Redefining \thepage to do anything other than return a page number is a really bad idea. See the answers to this question tex.stackexchange.com/q/3731/627 and squelch the page numbers by defining a new page style (eg with the fancyhdr package). –  Lev Bishop Mar 31 '12 at 18:18
    
etextools seems to cause problems with biblatex, is there another way to use something like squelchstyle? –  maetra Mar 31 '12 at 19:57
    
nice, that does the job I was looking for –  maetra Mar 31 '12 at 20:45
    
Is there any way to get this working with latex -> dvips -> ps2pdf (GhostScript)? –  Markus Schmassmann May 9 '12 at 19:18
