# An 'abstract' at the start of every chapter?

I am using the book document class and what I would like to do is to have a abstract like text at the start of every chapter (in smaller font outlining what will happen in the chapter, etc.). I don't have a problem changing to amsbook if that helps in anyway.

The memoir document class has a built in chapterprecis which looks like it does what you want... –  Seamus Sep 25 '10 at 17:24
I see but then I have never worked with the memoir class, it seems so overly complicated ... –  Hesam Sep 25 '10 at 20:09

Here is an example that uses one of the KOMA-Script classes to achieve a similar effect:

\documentclass[pagesize=auto, version=last, chapterprefix=true]{scrbook}

\usepackage{amsmath}
\usepackage{amsfonts}

\renewcommand*{\thesection}{\S\enspace\arabic{section}}
\renewcommand*{\dictumwidth}{0.7\textwidth}
\renewcommand*{\raggeddictum}{\raggedright}
\renewcommand*{\raggeddictumtext}{}

\setkomafont{dictumtext}{\normalfont\normalcolor\itshape\setlength{\parindent}{1em}\noindent}

\begin{document}

\setchapterpreamble{%
\dictum{%
The notion of prime number is fundamental in number theory.
The first part of this chapter is devoted to proving that every integer can be written as a product of primes in an essentially unique way.

After that, we shall prove an analogous theorem in the ring of polynomials over a field.%

}

\chapter{Unique Factorization}

\section{Unique Factorization in $\mathbb Z$}

\end{document}

Nice example of KOMA-Script. –  TH. Sep 25 '10 at 11:29
Thank you! This works. –  Hesam Sep 25 '10 at 20:14

You can define a similar abstract environment to your example using

\newenvironment{abstract}{\rightskip1in\itshape}{}


Just use \begin{abstract}...\end{abstract} after your \chapter and then start a \section after that.

I just use

\begin{quote}
{\small ...}
\end{quote}
