Page numbering in top corner

Question

I want to number my pages in the top corner, left or right - it depends on the side of book, the left page in book should have number on the left side and the right page on the right side. It works now only for one side (right or left).

Answer 1

New version: You can use \usepackage{scrlayer-scrpage}. And \ohead*{\pagemark} for outer pagemarks.

It works if your document is set up to be twoside.

Example:

\documentclass[10pt,a4paper,twoside]{article}
\usepackage[latin1]{inputenc}
\usepackage{scrlayer-scrpage}% sets pagestyle scrheadings automatically
\clearpairofpagestyles
\ohead*{\pagemark}% alternativ \ohead[\pagemark]{\pagemark}

\begin{document}
\begin{titlepage}
\begin{center}
Titel
\end{center}
\end{titlepage}
\thispagestyle{empty}
\cleardoublepage
\setcounter{page}{1}                 %counter =1
first page \newpage
second page \newpage
... next page
\end{document}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Accepted(old packages):

You can use \usepackage{scrpage2}. For example \pagestyle{scrheadings}. Set pagemarks inside or outside: \ihead[\pagemark]{\pagemark} or \ohead[\pagemark]{\pagemark}.

It works if your document ist set up to be twoside. Example:

\documentclass[10pt,a4paper,twoside]{article}
\usepackage[latin1]{inputenc}
\usepackage{scrpage2}
\pagestyle{scrheadings} % headline and footnote style:scrpage2-package
\clearscrheadings % clear headlines
\clearscrheadfoot % clear footnote
\ihead[\pagemark]{\pagemark} 
%\ohead[\pagemark]{\pagemark} %alternative

\begin{document}
\begin{titlepage}
\begin{center}
Titel
\end{center}
\end{titlepage}
\setcounter{page}{1}                 %counter =1
first page \newpage
second page \newpage
... next page
\end{document}
