I am saddened to hear of the recent death of Tefko Saracevic, one of the giants in information retrieval and relevance. A distinguished professor emeritus at Rutgers, his was a name known throughout the international LIS community. Although I frequently cited his work on relevance (as did almost all researchers in the area), I only had the opportunity to meet him once (in a frankly disastrous group interview with Rutgers iSchool faculty when I was on the job market) but it was certainly a highlight of that period for me so I was delighted later when one of my articles appeared as a reading in the syllabus for his Digital Libraries class.
Zbögom, Professor Saracevic!
