# Separate book into parts and chapters

I am working with the book document class and want to create something like this. Moreover, in the Table of Contents I want the "Part" to be under- and over-lined and not to be numbered. I think of using the \part command but don't know how to do this. Any help will be highly appreciated.

## Part I

1. Introduction.......... 1
2. Main results ......... 15

Could you elaborate a bit more as I'm not quite sure what your question is about. Is it a technical question about how to achieve the example TOC you give or is it more a design question? –  Benedikt Bauer Feb 22 at 19:23
Welcome to TeX.sx! Have a look at the tocloft package to design your Table of Contents. –  mafp Feb 22 at 19:26
I apologize. Basically, it is about making the \part to have no numbering in the contents page and be over and underlined –  john Feb 22 at 19:26

Hey this should get the job done. I would like to work on one thing, however.

1. Distance between upper line on part entry and lower entry should be exactly equal and easily changed.

I will update this code when I find a better solution.

\documentclass{book}
\usepackage{fontspec}
\usepackage{tocloft}

\renewcommand{\cftpartpagefont}{\bfseries}
\renewcommand{\thepart}{}%removes part roman numerals
\renewcommand{\cftbeforepartskip}{5mm}
\cftpagenumbersoff{part}%get rid of part page numbers
\renewcommand{\cftpartaftersnumb}{}%disable part number
\renewcommand{\thesection}{\arabic{part}}%add number to section without subnum
\renewcommand{\cftsecindent}{8mm}%control spacing between number and sec title
\renewcommand{\cftsecnumwidth}{4mm}%section indent
\renewcommand{\cftparskip}{4mm}%control line spacing

\begin{document}
\tableofcontents
\chapter{Elephants Eating (Chapter)}
\part{Peanuts}
\section{With Shells}
\part{Grass}
\section{Fresh}
\part{Leaves}
\section{From Oak Trees}

\end{document}

nice idea but it creates many errors. Is there any solution combined with the \input{chapter} command ? –  john Feb 24 at 12:28
Could you be more specific? What errors? By \input{chapter}, I assume you mean \input{filename}. Whether your files are separate or together, it should not affect the typesetting. Everything gets parsed as one file. Also, I vote up wouldn't hurt for my efforts :) I just gave away 200 points :( –  macmadness86 Feb 24 at 12:59
ok, the mistake was mine. I got it working as you suggested. Thanks :P –  john Feb 24 at 13:03
