Reflecting the focus but also range of their honorand’s work in medieval canon law in the era before Gratian, the essays in this volume explore the creation and transmission of canonical texts and the motives of their compilers but also address the issues of how the law was interpreted and used by diverse audiences in the earlier middle ages, with especial focus on the eleventh and early twelfth centuries. These issues have lain at the heart of Linda Fowler-Magerl’s distinguished body of scholarly work on judicial ordines and procedural literature, on the transmission of canonical texts and their formal sources before Gratian, and perhaps most especially her pioneering role in the creation of a database of canon law manuscripts before Gratian now published as Clavis canonum. Linda Fowler-Magerl’s work has fundamentally transformed our understanding of canonistic activity in the era before Gratian and its reception across the Church throughout Europe.

Individually the scholars whose studies are included in this volume offer new viewpoints on several key issues and questions relating to the creation of canonical texts, the concerns of their compilers and the transmission of their work, as well as the use of such texts by readers with the most various interests in the period. As a whole, the volume contributes to an understanding of the increasing importance of the written law for a far wider circle than Roman reformers and local advocates. These issues are especially highlighted by the editors’ introduction.
