<p>It is off-topic because it isn't about <a href="https://stats.stackexchange.com/help/on-topic">statistics, machine learning, etc</a>; but having access to a given reference. It would also be kind of a private question which is of low interest to the community.</p>

<blockquote>
  <p>I'd regard it as off-topic; it's not a question on statistics / machine learning but on access to papers. If you were to ask on chat that might be okay (e.g. if you wanted to know if someone could check some detail in a paper for you; asking to be supplied with a paper you didn't have legitimate access to would not be okay there either).</p>
