# Is it possible to add \chapter after a few \part's at the same level of hierarchy?

Consider the following code:

\documentclass{scrbook}
\usepackage[bookmarks, bookmarkstype=toc]{hyperref}

\begin{document}

\tableofcontents

\chapter{Introduction}

\part{First part}
\chapter{First chapter}
\chapter{Second chapter}

\part{Second part}
\chapter{Third chapter}
\chapter{Fourth chapter}

\chapter{Conclusion}

\end{document}


In the resulting PDF both tables of contents (the one produced by \tableofcontents and the list of PDF bookmarks) have the following hierarchy:

Introduction
First part
- First chapter
- Second chapter
Second part
- Third chapter
- Fourth chapter
- Conclusion


Is it possible to put 'Conclusion' at the same level of hierarchy with 'Introduction', 'First part' and 'Second part'?

If you want to adapt only the bookmarks: Either use bookmark instead of hyperref (it will load hyperref internally)

\usepackage{bookmark}
...

\bookmarksetup{startatroot}
\chapter{conclusion}


Or

\makeatletter
\def\toclevel@chapter{-1}
\makeatother
\chapter{Conclusion}

Thank you, both of your methods work. There is only one issue: no empty line between 'Fourth chapter' and 'Conclusion' in ToC (to visually separate them), which I fixed by adding \addtocontents{toc}{\protect\vspace*{\baselineskip}\protect} before \chapter{conclusion}. –  Bogdan Mar 3 '11 at 12:51
\chapter*{Conclusion}

If you want to add a "Conclusion" that is at the same level of hierarchy as your "First part" and your "Second part", then I suggest to use \part*{Conclusion}.
\part* does not put the part in the ToC; and, moreover, I'd prefer a chapter, not a part. –  Bogdan Mar 3 '11 at 12:40
@Bogdan: You can combine \part*{Conclusion} and (from @Herbert's answer) \addcontentsline{toc}{part}{Conclusion}. If you prefer \chapter, see @Ulrike's answer. –  lockstep Mar 3 '11 at 12:47
