When I group my mainmatter to prevent it of inserting a blank page, my chapter numbering dissapears as well.

I can't seem to find any work-around or even why this is happening.

\documentclass[a4paper,10pt,twoside,twocolumn,openany]{book}
\usepackage{lipsum}

\begin{document}
  \frontmatter
  \tableofcontents


{
    \renewcommand{\cleardoublepage}{\newpage}
    \mainmatter
  }
  \chapter{Two columns}
  \lipsum[1-5]


\chapter{Two columns again, but it's not}
  \lipsum[1-5]
\end{document}

The moment I remove the curly braces, it starts working again.

  • The grouping here voids your \renewcommand and whatever \mainmatter does. What is it that you actually want to achieve? – Werner Dec 14 '21 at 23:41
  • I used this to remove a blank page when the front matter has an odd number of pages.

    I followed the instructions of the linked answer.

    When looking at the document classes, I think 'report' fits better for my use case, as it does not have the frontmatter, mainmatter and backmatter

  • as the comment under the answer you referenced indicates, that is a bad example to follow, – David Carlisle Dec 15 '21 at 01:07

You can store whatever \cleardoublepage does and restore it after calling \mainmatter:

enter image description here

\documentclass[twoside,twocolumn,openany]{book}

\usepackage{lipsum}


\begin{document}


\frontmatter
\tableofcontents


\let\oldcleardoublepage\cleardoublepage
\renewcommand{\cleardoublepage}{\newpage}
\mainmatter
\let\cleardoublepage\oldcleardoublepage


\chapter{Two columns}
\lipsum[1-5]


\chapter{Two columns again}
\lipsum[1-5]


\end{document}

  • This does solve my problem. Another solution to achieve what I needed was to remove the 'twoside' option or change from 'book' to report. – Mathieu Dec 17 '21 at 16:02
