Html5 helps to use semantic tags, but only in some cases.
Dates
I.g. for a date you can use <time>
<p>La conferenza si terrà il <time datetime="2025-11-14">14 novembre 2025</time>.</p>Books
Far more complicated is the way for the books. There is not a tag such as <book>. Unfortunately, the Internet is not for the truth, but for commercial purposes, so you have to follow a very long and annoying way:

You could use a code like the following:
<div itemscope itemtype="http://schema.org/Movie">
<h1 itemprop="name">The Godfather</h1>
<h2 itemprop="alternateName">Il Padrino</h2>
<img itemprop="image" src="https://example.com/locandina_il_padrino.jpg" alt="Locandina del film Il Padrino">
