quaith writes "Quinn Dombrowski, a member of the University of Chicago's central IT staff, has been recording the graffiti left in the Joseph Regenstein Library Since September 2007. To date she has photographed and transcribed over 620 pieces of graffiti; over 410 of them are datable to within a week of their creation. She has now published in Inkling Magazine a statistical analysis of the entire graffiti collection covering such subjects as love, hate, despair, sex, anatomy, and temporal fluctuations of each of these. After November, both love and despair graffiti drop off significantly until spring, while sex graffiti reaches its one and only peak in December before declining for the rest of the school year.
