This page is dedicated to ongoing research into pre-Gratian canon law, principally those works associated with or attributed to Bishop Ivo of Chartres (+1115). It was revised and augmented in January 2006.

The project currently provides preliminary editions of the Tripartita, Ivonian Decretum, and the Panormia, along with manuscript information for each collection. There is also a preliminary handlist of Ivo's letters.
