You know what it is. For me it's the most extensive one I could lay my hands on.
Code:
<head>
<title>Werke 1</title>
<meta name="generator" content="pdftohtml 0.36"/>
<meta name="author" content="Roth, Joseph"/>
<meta name="keywords" content=""/>
<meta name="date" content="2017-01-20T12:05:05+00:00"/>
<meta name="subject" content="Das journalistische Werk"/>
<link href="stylesheet.css" rel="stylesheet" type="text/css"/>
<link href="page_styles.css" rel="stylesheet" type="text/css"/>
<link href="font_styles.css" rel="stylesheet" type="text/css"/>
</head>
Necessary is only this (in an ePub), I think. What do you think?
Code:
<head>
<title>Werke 1</title>
<link href="stylesheet.css" rel="stylesheet" type="text/css"/>
</head>
Sometimes instead of title e.g.
Werke 1 is just put inside
unknown. What's the difference?
