The volume examines the proliferation of inventorying models and practices as cultural techniques of knowledge organization and production during the long nineteenth century. While inventories are still broadly treated as raw data and unprocessed source materials, the book shows how they function as complex media formats, intersecting and interfering with other material techniques to produce, store, distribute, organize and process cultural information. How do inventories work against and in dialogue with other media of collection, storage and retrieval such as catalogs, indexes, bibliographies, and archives; what new media configurations do techniques of inventorying enable and how, in turn, are such techniques shaped by the media channels and formats they employ; what is at stake in the critical effort of "taking stock", whether as commercial, bureaucratic, literary, historiographical, or scientific operations; finally, what do such operations tell us specifically about the production and circulation of knowledge in the German nineteenth century?
