[Tex/LaTex] Headers in book format

capitalizationheader-footer

I am writting my thesis. I don't want the headers in each chapter to appear just in capital letters. Can I override the class file to get the header as " My First Chapter"?

Best Answer

Alternative using fancyhdr:

\documentclass{book}
% book defaults
%  headers
%   even pages
%    left: page number
%    right: CHAPTER 1. MY FIRST CHAPTER
%   odd pages
%    left: empty
%    right: page number
%  footers: empty
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{} % clear all headers and footers
\renewcommand{\headrulewidth}{0pt} % remove rule between header and text
\fancyhead[LE,RO]{\thepage} % put page number in left header on even pages,
                            % right header on odd pages
\fancyhead[RE]{\nouppercase{\leftmark}} % remove uppercase on chapter title
\renewcommand{\chaptermark}[1]{\markboth{#1}{}} % remove "Chapter N." prefix

\usepackage{lipsum}

\begin{document}

\chapter{My First Chapter}

\lipsum[1-20]

\end{document}
