# How do I remove the chapter number from my Index 'chapter' in the ToC?

A professional indexer has done an index for my book. I have created a new index chapter, pasted and formatted the index into it's own chapter.

When I compile the book the ToC includes the Index with a chapter number e.g.

10 Last Chapter.....400
Bibliography.........410
11 Index...............415

I want it to look like this:

10 Last Chapter.....400
Bibliography..........410
Index....................415

That is with no chapter number.

Here is my MWE with some packages that my be pertinent:

\documentclass[paper=6.125in:9.25in,pagesize=pdftex,10pt]{scrbook}
\areaset[0.375in]{4.5in}{8in}
\KOMAoptions{numbers=noendperiod} % get rid of last dot in eg Figure 3.1.
\usepackage{natbib} % style bibliograprhy (citations)
\usepackage{tocloft}
\setlength{\cftsecnumwidth}{2.5em} % this adds a gap in 13.10 and 13.11
\begin{document}
\frontmatter
\mainmatter
\tableofcontents
\include{somechapter}
\bibliographystyle{ieeetr}
\raggedright
\clearpage
\bibliography{somebibdeskfile}
\include{index}
\end{document}

• Without seeing inside the actual file, my guess is that in the index file, change from chapter{Index} to chapter*{Index} – Nicholas Hamilton May 26 '13 at 2:16
• Good idea but it removes the Index listing entirely from the TOC. The index.tex file has this code \chapter{Index} and then some formatting code, so it's very basic. – BruceMcG May 26 '13 at 2:22
• Add \backmatter before \include{index}. – lockstep May 26 '13 at 2:25

As you're using the scrbook class (it would also work for, e.g., book or memoir), you may simply add \backmatter before \include{index}. This way, any following chapters won't be numbered, but will still be added to the ToC (and feature correct headers).

You can also do one of two things:

• A general fix for adding chapters to ToC sans numbers: use \chapter*{index} then include the index title in the ToC while also allowing proper linking (e.g. if using hyperref package) by adding the below:
\chapter*{Index}
\phantomsection

• Add \usepackage{makeidx} and \makeindex in document preamble. Exchange \printindex for \include{index}. Then redefine the index environment like so:
%Redefine the index environment
\makeatletter
\renewenvironment{theindex}{%
\renewcommand{\leftmark}{Index}
\chapter*{Index}
\phantomsecion
\vspace{1em}
\columnseprule \z@
\columnsep 35\p@
\index@preamble\par\nobreak
\thispagestyle{\indexpagestyle}\parindent\z@
\setlength{\parskip}{\z@ \@plus .3\p@}%
\setlength{\parfillskip}{\z@ \@plus 1fil}%
\begin{multicols}{2}%
\let\item\@idxitem
}{\end{multicols}\clearpage}
\makeatother

• You saved my day, because I have a very complicated Latex-Template and needed a solution for a simple glossary. – user7581 Nov 13 '15 at 13:51

Since you're using a koma class (scrbook), you can just use the koma index class option. For example:

% arara: pdflatex
% arara: makeindex
% arara: pdflatex
% arara: pdflatex
\documentclass[index=totoc]{scrbook}

\usepackage{makeidx}
\makeindex

\begin{document}
\tableofcontents

\chapter{Sample}

Some text with a sample\index{sample} entry.

\printindex
\end{document}


(Note that two extra LaTeX runs are required after the makeindex run to ensure the table of contents is up-to-date.)
