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?
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.
For KOMA-Script scrbook from version 3.19a (and most likely for other KOMA-Script classes, too), you need to patch \scr@startchapter instead of chapter:
\usepackage{etoolbox}
\makeatletter
\patchcmd{\scr@startchapter}{\if@openright\cleardoublepage\else\clearpage\fi}{}{}{}
\makeatother
\include adds page breaks before and after it.
\input instead. See When should I use \input vs \include? for details.
\documentclass{report}
\begin{document}
\chapter{foo}
{\let\clearpage\relax \chapter{bar}}
\chapter{baz}
\end{document}
use \cleardoublepage instead of \clearpage for a two sided document
\part in scrbook (as for me)
\vspace*{\fill} {\let\clearpage\relax\chapter*{Abstract}}
I have used this whenever I needed to add one chapter to the previous page:
\begingroup
\let\clearpage\relax
\chapter{My Chapter}
\endgroup
It doesn't change the rest of the chapters, or anything else in the document.
