Is it legal to teach a book in you tube
<p>I want to teach a subject using a book. </p>

<p>On the book there are copyrights</p>

<p>I dont get any payment for my videos, its free, i just want to teach the subject from a book i learn and publish the lessons in youtube for all. </p>

<p>Again, there is no money i will get from the videos. </p>

<p>Am i doing an ilegal thing? or its ok? </p>

<p>Copyright only protects expression, and does not give an author ownership over the subject matter. So you can teach "about" the book in any forum you want. The only limit pertains to actual copying, for example you can't convert the text of a book into some Powerpoint-like display and then run those slides as your video. You can do that for money, if you want. </p>
