The present volume of studies on the life and work of Moritz (Moshe) Steinschneider (1816-1907) seeks to modify the traditional view of Steinschneider as a "mere bibliographer" by revealing other dimensions of his scientific personality. Together, the articles show that Steinschneider's manifold scholarly activities were rooted in a well-defined scientific agenda, which modern readers do not easily recognize but which deserves to be recovered. This volume represents a first attempt to sketch Steinschneider's intellectual biography and highlights the continued significance of his work for Jewish studies. It is an important contribution to our understanding of the project of nineteenth-century Wissenschaft des Judentums and its lasting impact on contemporary scholarly practice.
