[Tex/LaTex] Table of contents: section number and title overlapping

amsbookhorizontal alignmenttable of contents

I have problem with creation of table contents.
A part of my code: 

\documentclass[a4paper]{amsbook}
\usepackage[cp1250]{inputenc}
\usepackage{polski}
\makeatletter
\renewcommand*\@seccntformat[1]{\csname the#1\endcsname.\enspace}
\makeatother
\usepackage[sf,bf,outermarks]{titlesec} 

\begin{document}
\tableofcontents
\chapter*{Introduction}
\chapter{(Chapter 1 - Title)}
\section{Section  - Title}
\section{Section  - Title}
\subsection{Subsection - Title}
\subsection{Subsection - Title}
\section{Section  - Title}
\section{Section  - Title}
\section{Section  - Title}
\subsection{Subsection - Title}
\subsubsection{Subsection - Title}
\subsubsection{Subsection - Title}
\subsection{Subsection - Title}
\subsection{Subsection - Title}
\section{Section  - Title}
\begin{thebibliography}{1}
\bibitem{1} Bibliography 1
\end{thebibliography}
\end{document}

and it shows like this
enter image description here
as you can see, text overlapping.

How can I change this?
How can I add the number of chapter before number of section?

[ Chapter 1. Title
1.1 Section title
1.2 Section title
….
Chapter 2. Title
2.1 Section title
2.2 Section title
…]

Best Answer

you are using amsbook. admittedly, the implementation of tables of contents is faulty. leaving aside the reasons for that (fixing it is something that is in the list for the next upgrade, which unfortunately hasn't been scheduled yet), the ams has a package that will allow you to adjust the format to something more suitable.

since the package is not publicly posted, please send a message to tech-support@ams.org requesting it.

the package is not what we would call "industrial strength", and the methods used are not how the problems should be fixed when incorporated directly into amsbook. for these reasons, it is made available only on request.
