Asking for only peer-reviewed publications reduced our results from 175 academic articles to 136 articles and eliminated the 2607 magazine articles entirely.

We can further reduce these academic article results by using the Subject Terms.  Each article has been assigned subject terms by someone who read the article and comprehended what it was about.  The articles with the subject term "Instant Messaging" are really about instant messaging; they don't just mention the term somewhere in the article.

Click now on Instant Messaging in the Subject Terms box, to the left of the article results.  This will narrow our results to just those articles that are primarily about instant messaging.
