<p>A reference request <em>could</em> be too broad. For example, some reference requests would run into the "too many possible answers" criterion for being overly broad.</p>

<p>As such, askers of such requests should take care to do what they can to narrow the scope of their question (e.g. make it clear what they know and what they need, for example, so that a book of about the right level and scope may be suggested).</p>
