creative-commons attribution licensing
Will using CC by-sa content in a book prevent me from holding copyright?
<p>I've been reading up a little bit on the CC by-sa license, because I found a really helpful Stack Exchange answer that I would like to use in a book that I am selling. This answer is really short (only about 30 words long), but I modified it a little bit. With that being said, if it only takes up a very small portion of my book, and is not the main idea of my book, would I still be able to sell it and prevent redistribution (not using the CC by-sa license)? I am fine with allowing redistribution of my paraphrase of the answer, which will only be a paragraph long in the entire book. The most similar question I could find is <a href="https://law.stackexchange.com/questions/41267/if-i-use-cc-by-sa-image-in-a-video-must-the-whole-video-be-cc-by-sa">If I use CC-BY-SA image in a video, must the whole video be CC-BY-SA?</a>, but that question is for unmodified content. Is a footnote with attribution (direct link to the answer) enough? Should I contact the person who wrote the answer? Thanks so much for the answers :D</p>
<p>edit, just realised how much I used &quot;answer&quot; in that paragraph, sorry</p>
<p>edit 2, would I be able to license only a section of my book under CC by-sa, and then provide attribution like so?<a href="https://i.stack.imgur.com/Ic4sz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ic4sz.png" alt="enter image description here" /></a></p>

<p>One cannot use a post <strong>relying</strong> on the CC-BY-SA license, without complying with the SA part, that is unless the entire work in which it is incorporated is released under the CC-BY-SA license.</p>
<p>In the absence of license permission, a would-be reuser is in the same position as if the source work had been published with &quot;all rights reserved&quot; that is with no permissions granted to anyone except to read it. The source work might be quoted
in such a way that it falls under fair use in the US, or a similar exception to copyright in other countries. Proper attribution will help the case for fair use. Or the source work might be rewritten suffici8ently that its use is not an infringement. Or one might ask the original author for specific permission, outside the CC license, which the author might choose to grant.</p>
