Start new chapter on same page

Question

I am using report document class. When I create a new chapter, it starts it on a new blank page in which only the chapter name appears.

I want to be able to start new chapters on the same page as the old chapter ends. Is there any way to do it?

Answer 1

The \chapter command internally uses \cleardoublepage and \clearpage to add page breaks. Use the etoolbox package to selectively change the definition of \chapter.

\documentclass{book}

\usepackage{etoolbox}
\makeatletter
\patchcmd{\chapter}{\if@openright\cleardoublepage\else\clearpage\fi}{}{}{}
\makeatother

\begin{document}

\chapter{foo}

Some text.

\chapter{bar}

Some text.

\end{document}

Note: This etoolbox hack also works for the report class and for the KOMA-Script classes scrbook and scrreprt.

Answer 2

\documentclass{report}
\begin{document}

\chapter{foo}
\begingroup
\let\clearpage\relax
\chapter{bar}
\endgroup

\chapter{baz}
\end{document}

use cleardoublepage instead of clearpage` for a two sided document
