Thomas Izbicki received a doctorate in medieval history at Cornell University (1973). He became an academic librarian in 1986. While serving as a librarian at Wichita State University, Johns Hopkins University and Rutgers University, he pursued research on the medieval Church, including canon law. His publications focus on Pius II, Juan de Torquemada OP, Nicholas of Cusa and the sacraments in canon law. Dr Izbicki's most recent book is Religion, Power, and Resistance from the Eleventh to the Sixteenth Centuries: Playing the Heresy Card, edited with Karen Bollermann and Cary J. Niederman (2014).
'The influence, construction, and use of medieval canon law is richly illuminated through such a focused study.' Kriston R. Rennie, Renaissance Quarterly
