Book excerpt: Catalog of Catalogs provides a comprehensive index of nearly 2,300 publications documenting the exhibition of Judaica over the past 140 years. This vast corpus of material, ranging from simple leaflets to scholarly catalogs, contains textual and visual material as yet unmined for the study of Jewish art, religion, culture and history. Through highly-detailed, fully-indexed catalog entries, William Gross, Orly Tzion and Falk Wiesemann elucidate some 2,000 subjects, geographical locations and Judaica objects (ceremonial objects, illuminated manuscripts, printed books, synagogues, cemeteries et al.) addressed in these catalogs. Descriptions of the catalog's bibliographic components, contributors, exhibition history, and contents, all accessible through the volume's five indices, render this volume an unparalleled new resource for the study of Jewish Art, culture and history.
