The papers in this volume all share an interest in the scholarly practices of premodern Muslim authors. They discuss and reflect on a variety of Muslim scholarly practices both within and beyond the scope of Kohlberg’s methods and fields of inquiry. Their topics range from the theoretical question of the permissibility of relying on books without proper training to reconstruction of no longer extant sources used by medieval authors. Also discussed are the ways in which authors adapted their sources as well as the impact of sectarian identity on the presentation of historical figures such as Jaʿfar al-Ṣādiq.
