title: LinkedIn People Profile API not returning publication/publisher for the publications field
body: <p>I'm using the LinkedIn People Profile API to return results from a user's profile after they grant permission, based on the PHP example at <a href="https://developer.linkedin.com/documents/code-samples" rel="nofollow">https://developer.linkedin.com/documents/code-samples</a>.</p>
  
  <p>Basically it works, and I am successfully retrieving results, and can use them.</p>
  
  <p>However, the publications field, described at <a href="https://developer.linkedin.com/documents/profile-fields#publications" rel="nofollow">https://developer.linkedin.com/documents/profile-fields#publications</a> is not returning all the information.</p>
  
  <p>My request code looks like:</p>
  
  <pre><code>$user = fetch('GET', '/v1/people/~:(first-name,last-name,location:(name,country:(code)),num-connections,headline,industry,specialties,summary,public-profile-url,email-address,interests,publications,languages,skills,three-current-positions,phone-numbers,main-address,twitter-accounts,primary-twitter-account,educations,num-recommenders)');
  </code></pre>
  
  <p>All the fields return results. The publications field also returns the publication title and date, but does not return any publication/publisher information, even though the profile clearly has the information in the profile.</p>
  
  <p>To debug, I'm using the following line of code:</p>
  
  <pre><code>print "&lt;br /&gt;&lt;br /&gt;publications: " . print_r(json_encode($user-&gt;publications), true);
  </code></pre>
  
  <p>That's what I used for all the other returned collections. I find that JSON format convenient for later scripting.</p>
  
  <p>All the other collections I'm returning seem to have complete information (insofar as entered in the profile), but for publications the results are just:</p>
  
  <pre><code>publications: {"_total":2,"values":[{"date":{"day":1,"month":7,"year":2010},"id":91608681,"title":"\"Universe 2 - Echoes of the Sun\" at Osaka Expo '90 (Part 2 of 4)"},{"date":{"day":1,"month":6,"year":1992},"id":91608683,"title":"\u201cAn Expositional Virtual Environment\u201d"}]}
  </code></pre>
  
  <p>As you can see, it returned information about 2 publications, but only the date and title (and id). There is no publication/publisher information returned. Yet for both publications, the date, title and publication/profile are entered. </p>
  
  <p>Can somebody give me a hint about the problem I might be having?</p>
  
  <p>Thanks,</p>
