How do I remove "Chapter N" from the chapters when using the book
document class?
This does not appear in the TOC (which I don't want, either).
But it appears at the beginning of a chapter, and on each page, in the header.
With the help of titlesec
:
\documentclass{book}
\usepackage{titlesec}
\usepackage{lipsum}
\titleformat{\chapter}[display]
{\normalfont\bfseries}{}{0pt}{\Large}
\begin{document}
\chapter{Test Chapter}
\lipsum[3]
\end{document}
Without titlesec:
\documentclass{book}
\usepackage{lipsum}
\makeatletter
\def\@makechapterhead#1{%
\vspace*{50\p@}%
{\parindent \z@ \raggedright \normalfont
\interlinepenalty\@M
\Large \bfseries #1\par\nobreak
\vskip 40\p@
}}
\def\@makeschapterhead#1{%
\vspace*{50\p@}%
{\parindent \z@ \raggedright
\normalfont
\interlinepenalty\@M
\Large \bfseries #1\par\nobreak
\vskip 40\p@
}}
\makeatother
\begin{document}
\chapter{Test Chapter}
\lipsum[3]
\end{document}
To customize the headers/footers, one option is to use the fancyhdr
package; a little example, suppressing the prefix "Chapter N" from the default headers, and with the text in normal case (no upper-case):
\documentclass{book}
\usepackage{titlesec}
\usepackage{fancyhdr}
\usepackage{lipsum}
\titleformat{\chapter}[display]
{\normalfont\bfseries}{}{0pt}{\Large}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[RE]{\leftmark}
\fancyhead[LO]{\rightmark}
\fancyhead[LE,RO]{\thepage}
\renewcommand\headrulewidth{0pt}
\renewcommand\chaptermark[1]{\markboth{#1}{}}
\renewcommand\sectionmark[1]{\markright{\thesection.\ #1}}
\begin{document}
\chapter{Test Chapter}
\section{Test Section}
\lipsum[1-20]
\end{document}
Another option for the headers/footers is to use the pagestyles
option for titlesec
and design the desired style:
\documentclass{book}
\usepackage[pagestyles]{titlesec}
\usepackage{fancyhdr}
\usepackage{lipsum}
\titleformat{\chapter}[display]
{\normalfont\bfseries}{}{0pt}{\Large}
\newpagestyle{mystyle}{
\sethead[\thepage][][\chaptertitle]{\thesection~\sectiontitle}{}{\thepage}
}
\pagestyle{mystyle}
\begin{document}
\chapter{Test Chapter}
\section{Test Section}
\lipsum[1-20]
\end{document}
Partial solution
Thanks to einpoklum's answer, I found that this
\titleformat{\chapter}[display]
{\bfseries\Large}
{\filright}
{1ex}{}[]
solves the problem for the chapter start.
But the page headers remain.
Full solution
It appears this did it. Thanks to Gonzalo Medina, for his answer, from where I exerted the code.
\usepackage[pagestyles]{titlesec}
\titleformat{\chapter}[display]{\normalfont\bfseries}{}{0pt}{\Huge}
\newpagestyle{mystyle}
{\sethead[\thepage][][\chaptertitle]{}{}{\thepage}}
\pagestyle{mystyle}
Now it looks the way I like. (The screenshots got dusty, for some reason.)

The 'Chapter N' text is the value of the \@chapapp
macro, defined in the book document class.
But... no need to tinker with that directly. See
How to create specific chapter style in book documentclass
it refers you to the titlesec package and to these pages, with which you can change the chapter heading style. One of the things you can do, specifically, is play with the way the number is displayed.
\thechapter
just produces the representation for the counter; the string "Chapter" comes from the internal \@chapapp
command.

I found adding an asterisk after chapter works, like this: \chapter*{Introduction}
Found on https://www-users.york.ac.uk/~pjh503/LaTeX/text.html
It worked for me.
To remove the "Chapter n", just need to add \setcounter{secnumdepth}{-1}
before the \begin{document}
Source:
The ctan package documentation says
@chapter | This macro is called when we have a numbered chapter. When secnumdepth is larger than −1 and, in the book class, @mainmatter is true, we display the chapter number. We also inform the user that a new chapter is about to be typeset by writing a message to the terminal.
%% example code in the documentation
790 \def\@chapter[#1]#2{\ifnum \c@secnumdepth >\m@ne
791 ⟨book⟩ \if@mainmatter
792 \refstepcounter{chapter}%
793 \typeout{\@chapapp\space\thechapter.}%
794 \addcontentsline{toc}{chapter}%
795 {\protect\numberline{\thechapter}#1}%
796 ⟨∗book⟩
797 \else
798 \addcontentsline{toc}{chapter}{#1}%
799 \fi
800 ⟨/book⟩
801 \else
802 \addcontentsline{toc}{chapter}{#1}%
803 \fi
For example, if you need to remove "Part N" for \part, then you change it for \setcounter{secnumdepth}{-2}
and so on.
\chapter*
command, not the\chapter
command.
