So hear I am, finishing up the lit review on an article I'll submit for publication in the coming month. One of the articles in this review made extensive mention of Saracevic's IR model. Based upon this, I go back and find the Saracevic article in question (which, thanks to holding on to my readings from Harry's class, I still had). Before it was all over, I had tied my work back to Saracevic, David Ellis, Carol Kuhlthau, and Peter Ingwersen. It was like taking LIS 510 all over again, 14 years later! Thank you, Harry, for doing such a good job preparing all of us to be librarians -- what you taught me very much has real world application in what I do today.
