<p>Recently I came across with a <a href="https://stats.stackexchange.com/questions/56385/good-resources-online-or-book-on-the-mathematical-foundations-of-statistics">question</a> that was asking for book recommendation in an expertise area related to statistic. Then, I was checking for duplicates and I realized among all book recommendation questions some of them were community wiki (e.g. <a href="https://stats.stackexchange.com/questions/1815/recommended-books-on-experiment-design">2</a>,<a href="https://stats.stackexchange.com/questions/27553/the-reference-book-for-statistics-with-r-does-it-exist-and-what-should-it-cont">3</a>,<a href="https://stats.stackexchange.com/questions/125/what-is-the-best-introductory-bayesian-statistics-textbook">4</a>) and some were not (e.g.,<a href="https://stats.stackexchange.com/questions/23849/good-starting-book-on-psychometrics">5</a>.<a href="https://stats.stackexchange.com/questions/51309/book-for-non-parametric-statistics">6</a>.<a href="https://stats.stackexchange.com/questions/49166/suggested-books-on-spatial-statistics">7</a>).</p>

<p>Logically, among the examples given above, the group of question classified as <em>community wiki</em> were the ones more upvoted, edited, etc, according to Cross Validated SE rules stated <a href="https://stats.stackexchange.com/privileges/community-wiki">here</a>.</p>

<p>Although there are specific rules to be followed regarding community wiki classification, there are also flexibility which I understand these question fits. For flexibility I mean the quotation bellow:  </p>

<blockquote>
  <p>Moderators can also choose to convert posts into community wiki mode if they feel it is appropriate for the question or answer. Once a post is made community wiki through any of the above ways, that mode cannot be removed (except through moderator intervention in extreme circumstances).</p>
</blockquote>

<p>Finally, once these type of questions have very similar objectives, do you think it is a good idea to standardize all of them to have community wiki status?</p>

<p>On the other hand, I know book recommendation questions are considered off topic in many SE sites (e.g.: Arqade, Ask Ubuntu, Engineering, Programmers, Server Fault, StackOverflow, SuperUser, Travel, among others). We have a different theme here in CV, but maybe their arguments are valid for us.</p>
