article style page layout in book class only for one page

Question

book class arranges the text as it is required for printing. The margins are set automatically. If we don't want that formatting, oneside option is available, but it changes the formatting of the document globally. I just want the titlepage environment of the document like it is in the article class. It should be horizontally centered like in the article class. It should also be vertically centered like in the book class. After exploring some answers on this site, I tried afterpage package, but didn't find it helpful. Can somebody help me to redefine titlepage environment?

\documentclass{book}
\usepackage{lipsum}
\title{Title}
\author{Niranjan}

\begin{document}
\begin{titlepage}
\maketitle
\end{titlepage}
\lipsum
\end{document}

Answer 1

Try this.

\documentclass{book}
\usepackage{lipsum}
\title{Title}
\author{Niranjan}

\newlength{\shift} \setlength{\shift}{0.2in}
\begin{document}
\addtolength{\oddsidemargin}{\shift} % shift text to the right
\begin{titlepage}
\maketitle
\end{titlepage}
\addtolength{\oddsidemargin}{-\shift} % shift text back to the left
\lipsum
\end{document}

The shift value of 0.2in looked OK to me but you may want to change it a little bit.
