注意到使用时，tex4ebook -f epub3kindle 预览器显示生成的 epub 为匿名。果然，它的 content.opf 有
<dc:creator>Anonymous</dc:creator>
这是在 Windows 上运行 TeXlive 2023（已更新）生成的
tex4ebook -f epub3 mwe_no_creator.tex
看起来mwe_no_creator.tex像
\documentclass{memoir}
\usepackage{lipsum}
\title{A Cool Anthology}
\author{S.~Guide}
\date{} % suppress normally-inserted date
\begin{document}
\maketitle
\thispagestyle{empty} % suppress page number on title page (!)
\frontmatter
\tableofcontents
\mainmatter
\chapter{Story A}{
Story A graf 1
Story A graf 2
\lipsum
\end{document}
在此文件上使用 pdflatex 会生成一个显示标题和作者的标题页。
看起来这似乎是一件很简单的事情，但我看不出我在这里做错了什么。欢迎提出建议。
顺便说一句，这是在没有 html tidy 的情况下运行的，因为我发现它似乎会引入很多 epubcheck 问题（如果没有 tidy，则生成的 epub 根据 epubcheck 是干净的）。

此问题似乎已在 的开发版本中修复tex4ebook。在我将更新版本发布到 CTAN 之前，您可以使用 的修复版本tex4ebook.sty：
