Remove chapter from header but page number stays intact

Question

I want to remove the title of a chapter from the header, but the page number must stay intact.

I'm using a the book class

\documentclass[11pt,a4paper,twoside,openright]{book}
\usepackage{lipsum}
\begin{document}
\chapter{Some title}
\lipsum
\end{document}

The script generates two pages. The second page contains a header, page number and title. Now I want to remove the title from that particular page.

-edit- I found out that you can use \thispagestyle{plain}, however when I use this the page number, which is located at the top right, is then placed at the bottom.

Answer 1

Assuming that you want to suppress the chapter name from the header lines of all pages (other than pages which contain the chapter title, which are set in a different pagestyle anyway), you could use the following code. It relies on the etoolbox package and its \patchcmd macro.

\documentclass[11pt,a4paper,twoside]{book} 
\usepackage{etoolbox}
\makeatletter
\if@twoside
   \patchcmd{\ps@headings}%
      {\@evenhead{\thepage\hfil\slshape\leftmark}}%
      {\@evenhead{\thepage\hfil}}{}{}
\fi
   \patchcmd{\ps@headings}%
      {\@oddhead{{\slshape\rightmark}\hfil\thepage}}%
      {\@oddhead{\hfil\thepage}}{}{}  
\makeatother
\pagestyle{headings}
\usepackage{lipsum}
\begin{document}
\chapter{Some title}
\lipsum[1-30]
\end{document}

If the twoside option is in effect, LaTeX will typeset the page numbers on the right-hand side of the header line on odd-numbered pages and on the left-hand side of the header line on even-numbered pages. If the oneside document option is set, all page numbers will be set on the right-hand side of the header line (and, of course, without the chapter name on the left-hand side of the header lines).

By the way, this code works with both the book (default document option setting: twoside) and the report (default document option setting: oneside) document classes.

Answer 2

Much easier solution (if I'm understanding the original question):

Just use \pagestyle{myheadings}

This will keep your footer, remove the title from your header, and keep the page number in your header.
