I'm completely new to using headers and am struggling to understand the options of the packages I'm using.

I took this header setup from a friend:

\documentclass[11pt,onecolumn]{book}
\usepackage{geometry}
\usepackage{fancyhdr,textcase}

\pagestyle{fancy}

\begin{document}
\title{Some title}
\maketitle

\chapter{The first chapter}
some text!
\section{The first section}
Some more text!

\end{document}


This file is a {book}, and what I'd like is for the left-page header to give only the current chapter, and the right-page header to give only the current section.

However, the header is currently the same on both pages and shows both the chapter and the section.

I'm sure this is a simple fix, but I'm having trouble knowing where to look for info.

thanks!

• Did you used twoside in documentclass option? i.e. \documentclass[twoside]{book}. – Jagath Jun 25 '16 at 17:27
• @jagathAR I'm using twoside in the geometry package, but that's all as far as I can tell. I'll update the code in the question with more info on whats in the latex header. – CBowman Jun 25 '16 at 17:29
• A minimal working example would be helpful. – Johannes_B Jun 25 '16 at 17:36
• @johannes_B good point... I've now added something which compiles. You'll have to add some dummy text to add extra pages to see the header, though. – CBowman Jun 25 '16 at 17:54

Maybe you are looking for

\documentclass[11pt,onecolumn]{book}
\usepackage{geometry}
\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhead[LE]{\nouppercase\leftmark}% LE -> Left part on Even pages
\fancyhead[RO]{\nouppercase\rightmark}% RO -> Right part on Odd pages

\usepackage{blindtext}% dummy text
\begin{document}
\title{Some title}
\author{Author}
\maketitle
\blinddocument
\end{document}


Note that I have used \geometry before \pagestyle{fancy}.

• Thanks, that did the trick. I had never considered that the ordering of things like \geometry{} in the preamble could be important! I'll have to watch out for that in future. – CBowman Jun 25 '16 at 19:17

Could you please check whether the following works for you:

\fancyhead{}


The MWE will now looks like:

\documentclass[11pt,onecolumn]{book}
\usepackage{geometry,lipsum}
\usepackage{fancyhdr,textcase}

\pagestyle{fancy}

\begin{document}
\title{Some title}
\maketitle

\chapter{The first chapter}
some text!
\section{The first section}
Some more text!

\lipsum\lipsum

\end{document}

• Tried it and it doesn't seem to change anything unfortunately. Don't know if it matters but i did clean out all the auxiliary files after the change. – CBowman Jun 25 '16 at 17:44
• Please add some text after \section{} and check next two pages. Add \usepackage{lipsum} in preamble and add \lipsum\lipsum after \section{} and check the pages. – Jagath Jun 25 '16 at 17:46
• @JagathAR: While this might be solution anyone seeing it has to build up a compilable document of this fragment -- this is not our preferred way of answering questions ;-) – user31729 Jun 25 '16 at 17:49
• @ChristianHupfer. Sorry. I have now put the MWE. – Jagath Jun 25 '16 at 17:52
• @JagathAR: The TeX.SX force is strong in you ;-) (+1) – user31729 Jun 25 '16 at 17:53
