非标题页上的作者信息

Question

我想在非标题页的页面上添加作者信息。

就像是

\documentclass[12pt,a4paper]{book}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage[left=2.00cm, right=2.00cm, top=2.00cm, bottom=2.00cm]{geometry}
\title{}
\author{}
\begin{document}
    \date{}
    \maketitle


    \chapter{New Chapter}
    Authors

    Institutions
\end{document}

作者信息需要放在章节标题下的章节页上。我该如何实现这一点？

Answer 1

的默认行为是删除在、和\maketitle中输入的值。您可以使用以下代码在删除之前捕获这些值：\title\author\date

\documentclass{book}

\title{A title}
\author{An author}
\date{\today}

\makeatletter
\let\oldmaketitle\maketitle
\renewcommand{\maketitle}{%
  \let\printtitle\@title
  \let\printauthor\@author
  \let\printdate\@date
  \oldmaketitle
}
\makeatother

\setlength{\parindent}{0pt}% Just for this example

\begin{document}

\maketitle

\chapter{A chapter}

Title: \printtitle \par
Author: \printauthor \par
Date: \printdate

\end{document}

以下 - 将内容存储在您以后可以访问的宏中 - 是一种等效的替代方法：

\documentclass{book}

\newcommand{\mytitle}{A title}
\newcommand{\myauthor}{An author}
\newcommand{\mydate}{\today}

\title{\mytitle}
\author{\myauthor}
\date{\mydate}

\setlength{\parindent}{0pt}% Just for this example

\begin{document}

\maketitle

\chapter{A chapter}

Title: \mytitle \par
Author: \myauthor \par
Date: \mydate

\end{document}
