<p>The tag <a href="https://stats.stackexchange.com/questions/tagged/references" class="post-tag" title="show questions tagged &#39;references&#39;" rel="tag">references</a> on Cross Validated doesn't seem to have any usage guidelines included.</p>

<p>An analogous tag "reference-request" on Math.StackExchange has the guideline that it should not be a standalone tag, i.e. the only tag used for a question. There are also explicit guidelines for other meta-tags: <a href="https://math.meta.stackexchange.com/questions/2498/the-meta-tags">https://math.meta.stackexchange.com/questions/2498/the-meta-tags</a></p>

<p>Would it make sense to have similar guidelines for Cross Validated? Or do such guidelines already exist (and I couldn't find them) but they are not written in the tag info for "references"?</p>

<p>I was looking for tags without any tag info or usage guidelines to edit and "references" came to mind as one thing to consider. Changes without consulting Meta usually are not approved. </p>
