<span id="unnumbered-_0026-appendix"></span><span id="index-unnumbered"></span>
<span id="index-appendix"></span>
<p>Use the <code>@unnumbered</code> command to start a chapter-level element
that appears without chapter numbers of any kind. Use the
<code>@appendix</code> command to start an appendix that is labeled by
letter (‘A’, ‘B’, …) instead of by number; appendices are also
at the chapter level of structuring.
</p>
<p>Write an <code>@appendix</code> or <code>@unnumbered</code> command at the
beginning of a line and follow it on the same line by the title,
just as with <code>@chapter</code>.
</p>
<span id="index-centerchap"></span>
<p>Texinfo also provides a command <code>@centerchap</code>, which is analogous
to <code>@unnumbered</code>, but centers its argument in the printed and HTML
outputs. This kind of stylistic choice is not usually offered by
Texinfo. It may be suitable for short documents.
</p>
<span id="index-Docbook-and-prefatory-sections"></span>
<span id="index-Preface_002c-etc_002e_002c-and-Docbook"></span>
<p>With <code>@unnumbered</code>, if the name of the associated node is one of
these English words (case-insensitive):
</p>
<div class="example">
<pre class="example">Acknowledgements Colophon Dedication Preface
</pre></div>
<span id="index-_003cacknowledgements_003e-Docbook-tag"></span>
<span id="index-_003ccolophon_003e-Docbook-tag"></span>
<span id="index-_003cdedication_003e-Docbook-tag"></span>
<span id="index-_003cpreface_003e-Docbook-tag"></span>
<span id="index-_003cchapter_003e-Docbook-tag"></span>
<span id="index-_003ctitle_003e-Docbook-tag"></span>
<p>then the Docbook output uses corresponding special tags
(<code><preface></code>, etc.) instead of the default <code><chapter></code>.
The argument to <code>@unnumbered</code> itself can be anything, and is
output as the following <code><title></code> text as usual.
