<p>While performing an action derived from another <a href="https://stats.meta.stackexchange.com/questions/1700/doubt-on-tag-recommendations">CV meta question</a> and re-looking this <a href="https://stats.stackexchange.com/questions/23696/how-to-learn-data-analysis">question</a>, I realized <a href="https://stats.stackexchange.com/questions/tagged/sources" class="post-tag" title="show questions tagged &#39;sources&#39;" rel="tag">sources</a> (5 threads) and <a href="https://stats.stackexchange.com/questions/tagged/resources" class="post-tag" title="show questions tagged &#39;resources&#39;" rel="tag">resources</a> (13 threads) have been used to mean <a href="https://stats.stackexchange.com/questions/tagged/references" class="post-tag" title="show questions tagged &#39;references&#39;" rel="tag">references</a> (245 threads). I saw "resources" was already <a href="https://stats.meta.stackexchange.com/questions/1007/tags-for-references">asked</a> to be a synonym in 2011 (no answers, though), but "sources" was not mentioned there.</p>
