# In book class, make the titlepage environment successively displayed

I use several titlepage environments on book document class as

\documentclass[openany]{book}
\begin{document}
\begin{titlepage}
\end{titlepage}
\begin{titlepage}
\end{titlepage}
\end{document}


but I want the title page successively displayed (just clear single page) instead of clear double page.

Since you don't use two column format, the simplest way is to redefine the titlepage environment:

\renewenvironment{titlepage}
{\clearpage\thispagestyle{empty}
\setcounter{page}{0}% Comment out if you don't want to reset the page number
}
{\newpage}

-

Use \patchcmd from the etoolbox package to change the definition of \titlepage.

\documentclass[openany]{book}
\usepackage{etoolbox}
\patchcmd{\titlepage}{\cleardoublepage}{\clearpage}{}{}
\begin{document}
\begin{titlepage}
