Use the values of \title, \author and \date on a custom title page

Question

I am trying to create a title page of my own.

Is there a way to make use of the \title, \author and \date commands inside the title page?

For instance:

...
\title{Something Cool}
\author{Cool Dude}
\date{\today}

\begin{document}
\begin{titlepage}

The title is \title
It was written by \author on \date

\end{titlepage}
\end{document}

Basically I just want to know if there is a way to leverage the information stored in \title, \author and \date inside the title page.

Answer 1

The \title, \author and \date macros save their argument into \@title, \@author, and \@date, respectively. You can use these macros after \makeatletter. Afterward, use \makeatother. Note that they are cleared by \maketitle.

\title{Example}
\author{Me}
\date{\today}
% ...
\makeatletter
\begin{titlepage}
The title is @title
It was written by @author\space on @date
\end{titlepage}
\makeatother

Answer 2

The titling package provides various user-friendly ways to modify title pages.

It provides the macros \thetitle, \theauthor and \thedate which can be reused anywhere in your document.

It allows you to have multiple instances of \title, \author and \date and \maketitle itself in a single document. (If you don't use titling, \maketitle clears the values of \@title, \@author and \@date [cf. Martin's answer] after it has used them.)

It also provides various hooks for modifying the formatting of all of the component parts.

Answer 3

I understand your question as follows: How can I access the values of the title, author, and date fields somewhere in the document. I suggest the following MWE as an answer, which dispenses with the need to use \makeatletter ... \makeatother outside of the preamble:

\documentclass{article}
\title{Something}
\author{Somebody}
\date{Sometime}

\makeatletter
\let\newtitle\@title
\let\newauthor\@author
\let\newdate\@date
\makeatother

\begin{document}
\maketitle

Later in the document \ldots we access the variables again:
\newtitle, \newauthor, and \newdate.

\end{document}

Answer 4

There exists a package exactly for this purpose: authoraftertitle

\documentclass{article}
\usepackage{authoraftertitle}
\title{Something}
\author{Somebody}
\date{Sometime}

\begin{document}
\maketitle

Later in the document \ldots we access the variables again:
\MyTitle, \MyAuthor, and \MyDate.

\end{document}

Answer 5

Another possibilty is to define metadata. Something like

\def\myauthor{Author} % Author
\def\mycoauthor{} % co-author
\def\mytitle{Title} % title
\def\mydate{Date} % date
%....
\begin{titlepage}

The title is \mytitle
It was written by \myauthor on \mydate

\end{titlepage}
