Is it legal to profit from explaining a book&#39;s content?
<p>I was wondering if explaining a book's contents on a potentially monetized Youtube channel is similar to simply being a tutor or teacher if the book is freely available online via &quot;pressbooks&quot;. The book is under the following terms:</p>
<blockquote>
<ol>
<li><p>Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.</p>
</li>
<li><p>NonCommercial — You may not use the material for commercial purposes.</p>
</li>
<li><p>ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.</p>
</li>
</ol>
</blockquote>
<p>I definitely plan to provide a link to the book, but it's the 'noncommercial' part I was concerned about. Also, would it be ok to also include the definitions mentioned in the book, or would I have to write it in my own words?

<h2>That licence does not allow you to do what you want</h2>
<p>It’s a non-commercial licence and your usage is commercial (making money).</p>
<h2>You don’t need a licence to perform commentary or review of a book</h2>
<p>Providing that you use as little material as necessary from the original work, commentary and review is one of the exceptions to copyright carved out by fair dealing in most English speaking jurisdictions.</p>
<p>In the USA, the fair use exemption is not so clear as it involves a four factor balancing test. Your planned use is in favour of being fair use, your commercialisation is against.</p>
