# Changing fancyhdr for a few pages

I am writing a book with several parts and chapters that has a general introduction. I defined a header style for most of the book, that I can easily locally disable for a few pages with \pagestyle{empty}. The header has my name in even pages and the chapter mark (Chapter XX) in odd pages.

Now I would like to have a different kind of header for the introduction to avoid having an ugly "Chapter 0" as a header. I want the header to have my name in even pages and "introduction" in odd pages.

I defined a new style using fancyhdr. However nothing seems to work. After a few pages, I get the "Chapter 0" back in the introduction, and it lasts until the next chapter, although I have cleared the page. Can you please tell me wat is wrong in my MWE?

  \documentclass[12pt, A4]{book}

\usepackage{tocbibind}
\usepackage{blindtext}
\usepackage{emptypage}
\usepackage{fancyhdr}

\fancypagestyle{style1}{
\fancyfoot[CE]{Me}
\fancyfoot[CE,CO]{\thepage}
}

\pagestyle{fancy}
\fancyhf{}
\fancyfoot[CE,CO]{\thepage}

\begin{document}

{\pagestyle{empty}
\tableofcontents
\clearpage}

\clearpage
{\pagestyle{style1}
\chapter*{Introduction}

\Blindtext

Use \leftmark in the header. There is also a \rightmark. However, here in book-class, with default options, \leftmark would hold the chapter-name, with some formatting. This can be changed of course.

A few places throughout your document, you need to change what is in the header, as you haven't yet defined a non-starred \chapter. Then we can update \rightmark with \markkright, but there is no \markleft-command available. A shame really, could be useful. \markboth{left}{right} could be used here, though.

## Suggestions

• Instead of issuing new \pagestyle for when you want a single page to be different. Use \thispagestyle, which only changes the style for that one page. Have the first/main \pagestyle in the preamble, keeps it a bit tidier. Content and settings should in my opinion be separated as much as possible.
• You don't need so many \clearpages. In book-class, the default option is openright, which means that every chapter will start at only right-hand sides.

Code

  \documentclass[12pt, a4paper]{book}

\usepackage{tocbibind}
\usepackage{lipsum}
\usepackage{emptypage}
\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhf{}
\fancyfoot[CE,CO]{\thepage}
\pagestyle{fancy}
\begin{document}

\thispagestyle{empty}
\tableofcontents}
\clearpage

\chapter*{Introduction}\markboth{Introduction}{}
\lipsum[1-9]
\clearpage

\part{Thing} \markboth{Part thing}{}

\lipsum[1-10]

\chapter{Thing thing}

\lipsum[1-7]
\chapter{thingthingthing}

\lipsum[1-8]
\end{document}

• Thank you, this works brilliantly, except that I get a header for the TOC – Doon_Bogan Jun 24 '16 at 14:23
• Oh, I see what you mean now. Use {\renewcommand\addcontentsline[3]{} \tableofcontents} The reason it got added was that you specified it with the package tocbibind – Runar Jun 25 '16 at 4:17

Here is a solution. as suggested in above answer use of \leftmark is recommended.

You can do what you want in once using \fancyhead[CO]{\ifnum\value{chapter}>0 \chaptername \ \thechapter\else\leftmark\fi}

if you want you can do \fancyhead[CO]{\ifnum\value{chapter}>0 \chaptername \ \thechapter\ \fi\leftmark}

\documentclass[12pt, a4paper]{book}

\usepackage{tocbibind}
\usepackage{blindtext}
\usepackage{emptypage}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyfoot[CE,CO]{\thepage}
