# How do I stop indenting first paragraphs when using amsbook style? [duplicate]

I'm using amsbook style and I'd like first paragraphs to be not indented - what can I add to the header to do this?

I don't want to use /noindent as then I'd have to use it all the way through my 200 page document, I'd prefer to do it automatically.

• \noindent can be invoked before the first paragraph. Sep 28, 2013 at 12:40
• But I'd prefer not to have to add that throughout my entire thesis. Sep 28, 2013 at 12:42

You need to redefine \section. The relevant part of amsbook.cls is

\def\section{\@startsection{section}{1}%
\z@{.7\linespacing\@plus\linespacing}{.5\linespacing}%
{\normalfont\bfseries\centering}}


You want this:

\makeatletter
\def\section{\@startsection{section}{1}%
\z@{-.7\linespacing\@plus\linespacing}{.5\linespacing}%
{\normalfont\bfseries\centering}}
\makeatother


Note the negative value -.7.

Use\makeatletter ... \makeatother if you don't want to edit amsbook.cls.

\documentclass{amsbook}
\begin{document}
\noindent Don't be lukewarm. If you cannot be the best, be the worst.

Second paragraph here\ldots
\end{document}


• Yes, that would work but I'd have to do it throughout my whole document and I'm sure there is a better way. Sep 28, 2013 at 13:14
