I use LaTeX with the document class book. I´d like a blank page between chapters but it works only after Chapter 1. I've tried to force a blank page with \newpage, \clearpage and \cleardoublepage and nothing happens.

How can I add a blank page? Why are they not included automatically after chapters?

Here is my document.tex:

\documentclass[a4paper,11pt]{book}

\usepackage{./estilos/estiloBase} 
\usepackage{./estilos/colores}  
\usepackage{./estilos/comandos}

\graphicspath{{./imagenes/}}

\begin{document}

\pagestyle{empty}
\input{portada.tex}
\cleardoublepage

\input{primerahoja.tex}
\cleardoublepage
\pagestyle{plain}

\frontmatter 

\input{previo.tex}
\cleardoublepage

\tableofcontents
\listoffigures
\listoftables

\mainmatter 

\chapter{Introducción}
\label{cap:introduccion}
\input{cap1.tex}

\chapter{Descripción general del proyecto}
\label{cap:descripcion}
\input{cap2.tex}

\chapter{Contexto}
\label{cap:contexto}
\input{cap3.tex}
...

\appendix
\cleardoublepage
\addappheadtotoc
\appendixpage
\chapter{Manual de usuario}
\label{cap:manusuario}

\backmatter

\chapter*{Software utilizado}
\addcontentsline{toc}{chapter}{Software utilizado}
\input{programas.tex}

\cleardoublepage

\addcontentsline{toc}{chapter}{Bibliografía y referencias}
\bibliographystyle{unsrt}
\bibliography{bibliografia}

\input{fdl-1.3.tex}
\end{document}
  • Welcome to TeX.SX! Chapters in book start on a recto page (the page to the right when you open a book), so an empty page is only added if the previous chapter ended on a recto page, then the verso page between will be left blank. – Torbjørn T. May 27 '14 at 21:20
  • An easy option here would be to use \let\oldchapter\chapter \renewcommand{\chapter}{\clearpage\mbox{}\clearpage\oldchapter} so that the "empty page generation" is incorporated in your \chapter command. Note that this should give you an empty page, always. – Werner May 27 '14 at 21:31
  • So if I'm going to print this document (my thesis), What's the most recommended way? start chapters on a recto page always although a previous chapter finish on verso page? or left two blank pages between chapters in this case? – Jorge Antequera May 27 '14 at 21:41
  • The standard approach would be either (1) start on recto, leaving a blank only if the previous chapter finished on recto or (2) start on new page without ever leaving a blank page after the previous chapter. I've never seen a book which skipped a page to put the new chapter on verso. Nor have I seen one which skipped two pages to get back to recto. (But there are many books I've not seen...) For a thesis, I would choose option (1) if you don't have guidelines to the contrary. – cfr May 27 '14 at 22:00
  • @JorgeAntequera: For this one would use the openright option of book. It's included by default, so you technically don't have to change a thing. – Werner May 27 '14 at 22:55

The book document class issues openright by default, which means that \chapter pages will start on a recto (right) page (typically an odd numbered page):

enter image description here

Therefore, it may be that some chapters end without a blank page while others end with one, depending on whether the subsequent page is recto or verso. If you wish to always have a blank page before a chapter, then you should pass the openany option to the document class and add the following to your preamble:

\let\oldchapter\chapter % Make a copy of \chapter
\renewcommand{\chapter}{%
  \clearpage% Clear the page and flush any pending floats
  \mbox{}% Put something on the new page
  \clearpage% Issue another \clearpage (perhaps not necessary, as \oldchapter may issue it)
  \oldchapter}% Regular chapter

The comments above describes the update to \chapter.

Most books are set with openright with the chapters starting on recto in the twoside document option. Otherwise, if you're not printing your document in twoside mode, then openany would be a good option.
