Hello,

I'd like to print out the document title at certain points in the document. For this, I'd like to print out (I thought of \thetitle but it doesn't work) the title I defined via \title. Just to clarify: It's a string of words, maybe only one word, but it's not the titlepage.

Is that possible?

I've searched for a solution for good 15 minutes now, but it seems my queries were too general for Google and Bing.

The arguments of \author and \title are stored in special internal macros. Save them to another macro and you can use them wherever you want. If I understand you right, the code below should do what you want.

Code: Select all

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\title{Using the document title wherever needed}
\author{Montag}

\makeatletter
\let\thetitle\@title
\let\theauthor\@author
\makeatother

\begin{document}
  \maketitle

  The title of this short document is: »\thetitle«.
  Author of this document is: \theauthor.
\end{document}

Note that the sequence of commands is very important. The title and author have to be declared first to make the new commands work.

Thanks a lot, Thorsten, that is what I looked for.

Is there a way these internal commands could be nullified somehow? I just noticed in one document the author and title field are empty and I can't figure out why, that's why I'm asking.

Do you mean accidentally or user intended? Can you give a short example?

Accidentally!

Can you give a short example?

I'd like to, but like I said, I defined the title and author like you showed above and so far I had no problems.
But in one document of mine, the fields stay empty. And I already made a "folder search" in TXC and can't find some second definitions for \title{This is the title} and \author{My name} anywhere. So I guess this code

Code: Select all

\makeatletter
\let\thetitle\@title
\let\theauthor\@author
\makeatother

gets re-set to zero or empty later on.
I don't really understand it. :/

EDIT:
Got it. Clear case of Luser. :/
I accidentally switched the order of the commands you provided in your answer, in which you also underlined the importance of their order.

They're cleared by \maketitle, to save memory.

You could do

Code: Select all

\makeatletter
\let\m@ketitle=\maketitle
\def\maketitle{\let\@@author=\@author\let\@@title=\@title
\m@ketitle
\let\author=\@@author\let\title=\@@title}
\makeatother

(and then use \author and \title for those values)
