<title>UK TeX FAQ -- question label secnumdep</title>
</head><body>
<h3>Unnumbered sections in the Table of Contents</h3>
<p>The way the relevant parts of sectioning commands work is exemplified
by the way the <code>\</code><code>chapter</code> command uses the counter <code>secnumdepth</code>
(described in Appendix C of the LaTeX manual):
<ol>
<li> put something in the <code>.aux</code> file, which will appear in
the <code>.toc</code>;
<li> if the <code>secnumdepth</code> counter is greater than or equal to
zero,
increase the counter for the chapter and write it out.
<li> write the chapter title.
</ol>
Other sectioning commands are similar, but with other values used in
the test.
<p>So a simple way to get headings of funny 'sections' such as prefaces
in the table of contents is to use the counter:
<blockquote>
<pre>
\setcounter{secnumdepth}{-1}
\chapter{Preface}
</pre>
</blockquote>
Unfortunately, you have to set <code>secnumdepth</code> back to its usual
value (which is 2 in the standard styles) before you do any 'section'
which you want to be numbered.
<p>Similar settings are made, automatically, in the LaTeX book class by
the <code>\</code><code>frontmatter</code> and <code>\</code><code>backmatter</code> commands.
<p>The value of the counter <code>tocdepth</code> controls which headings
will be finally printed in the table of contents. This normally has
to be set in the preamble and is a constant for the document. The
package <i>tocvsec2</i> package provides a convenient interface to
allow you to change the <code>secnumdepth</code> and/or the
<code>tocdepth</code> counter values at any point in the body of the
document; this provides convenient independent controls over the
sectional numbering and the table of contents.
<p>The package <i>abstract</i> (see
<a href="FAQ-onecolabs.html">one-column abstracts</a>) includes an option
to add the <code>abstract</code> to the table of contents, while the
package <i>tocbibind</i> has options to include the table of
contents itself, the <code>bibliography</code>, <code>index</code>, etc., to
the table of contents.
<p>The <i>KOMA-Script</i> classes have commands <code>\</code><code>addchap</code> and
<code>\</code><code>addsec</code>, which work like <code>\</code><code>chapter</code> and <code>\</code><code>section</code> but
aren't numbered. The <i>memoir</i> class incorporates the facilities
of all three of the <i>abstract</i>, <i>tocbibind</i> and
<i>tocvsec2</i> packages.
