<li>How does this work?</li>
</ul>
<p>Clicking the &quot;cite&quot; button populates some elements of the webpage to BibTeX and amsrefs citation formats.</p>
<ul>
<li>Are they indexed later?</li>
</ul>
<p>Indexed where? For whom? For what purpose? Some service somewhere probably scrapes these citations. On the other hand, these citations don't appear in Google Scholar, either because this Q&amp;A site doesn't fit Google Scholar's criteria for inclusion, or Google simply hasn't gotten around to including it.</p>
<ul>
<li>Why CV has this option while others don't?</li>
</ul>
<p>Basically, this thread is why we have a &quot;cite&quot; button -- we asked and SE implemented it: <a href="https://stats.meta.stackexchange.com/questions/4870/is-there-no-cite-tag-to-generate-a-bibtex-misc-entry-for-answers-on-cross-valida">Is there no cite tag to generate a bibtex MISC entry for answers on Cross Validated?</a> Other sites haven't asked for citation buttons, or SE has not chosen to implement it for them.</p>
