<h3>Really blank pages between chapters</h3>
<p><i>Book</i> (by default) and <i>report</i> (with <code>openright</code> class
option) ensure that each chapter starts on a right-hand (recto) page;
they do this by inserting a <code>\</code><code>cleardoublepage</code> command between
chapters (rather than a mere <code>\</code><code>clearpage</code>).  The empty page thus
created gets to have a normal running header, which some people don&rsquo;t
like.
<p>The (excellent) <i>fancyhdr</i> manual covers this issue, basically
advising the creation of a command <code>\</code><code>clearemptydoublepage</code>:
<blockquote>
<pre>
\let\origdoublepage\cleardoublepage
\newcommand{\clearemptydoublepage}{%
  \clearpage
  {\pagestyle{empty}\origdoublepage}%
}
</pre>
</blockquote><p>
The &ldquo;obvious&rdquo; thing is then to use this command to replace
<code>\</code><code>cleardoublepage</code> in a patched version of the <code>\</code><code>chapter</code> command.
(Make a package of your own containing a copy 
of the command out of the class.)  This isn&rsquo;t particularly difficult,
but you can instead simply subvert <code>\</code><code>cleardoublepage</code> (which isn&rsquo;t
often used elsewhere):
<blockquote>
<pre>
\let\cleardoublepage\clearemptydoublepage
</pre>
</blockquote><p>
Note: this command works because <code>\</code><code>clearemptydoublepage</code> uses a copy
of <code>\</code><code>cleardoublepage</code>: instructions on macro programming

<a href="FAQ-patch.html">patching techniques</a> explain the problem and
why this is a solution.
<p>Note that the <em>KOMA-Script</em> replacements for the
<i>book</i> amd <i>report</i> classes (<i>scrbook</i> and
<i>scrreprt</i> offers class options <code>cleardoubleempty</code>,
<code>cleardoubleplain</code> and <code>cleardoublestandard</code>
(using the running page style, as normal) that control the appearance
of these empty pages.  The classes also offer do-it-yourself commands
<code>\</code><code>cleardoubleempty</code> (etc.).
<p>The <i>memoir</i> class (and the <i>nextpage</i> package)
provide commands <code>\</code><code>cleartooddpage</code> and <code>\</code><code>cleartoevenpage</code>,
which both take an optional argument (the first, with no argument,
being an equivalent of <code>\</code><code>cleardoublepage</code>).  One can achieve
&lsquo;special&rsquo; effects by putting commands in the optional argument: the
<code>\</code><code>clearemptydoublepage</code> we&rsquo;re after would be achieved by
<code>\</code><code>cleartooddpage[</code><code>\</code><code>thispagestyle{empty}</code><code>]</code>.  The
commands will also serve if you want the surreal effect of &ldquo;This page
intentionally left blank&rdquo; in the centre of an otherwise empty page.
